My name is Mahan and I am of Persian origin.

In today's highly competitive world where technology is improving every day, organisations need great minds with a deep understanding of a plethora of industries. I studied my undergraduate degree in Mechanical engineering where I familiarised myself with thermodynamics, thermofluids, solid mechanics and mathematics for engineers, which can be classed as the foundation modules for engineering.

During the past four years I have developed my skills in different types of industrial engineering software such as ANSYS, ABAQUS, Pro Engineering (Creo) and Solidworks. These skills were obtained by carrying out real projects within the engineering field. The great thing about mechanical engineering is that students are trained to keep an open mind. Skills I have gained from my years of study are applicable in many fields, such as automotive, renewable energy, oil & gas, aerospace and so on. For the past year I have studied an MSc in Advanced Mechanical Engineering, following on from my undergraduate degree and to enhance my level of understanding and capabilities. Now I see myself as someone who is confident to enter the industry and deliver the modern skills I have acquired by undergoing experimental and theoretical research and analysis.

ABOUT ME

I undertook this project working alongside Chapman Ventilation who are in partnership with my university. This project is due to be completed on 27/05/2016. Electrostatic precipitator has been the topic of research for many years. this device simply filters the polluted air generated by whether factories or restaurant using electrostatic fields. The matters become more complicated when the device is going to be used in food industry for certain rules and regulations. The purpose of this device is to keep the environment clean. However the current technology creates a high electrostatic field. The interaction of the flow with this electrical field will generate ozone which is know to be harmful for human health.

In essence my project involves using CFD (ANSYS) to model an Electrostatic Precipitator and from that find a way for the system to carryout an efficient particle separation (filtering smoke and grease) in parallel with reduction of the amount of ozone generated by a typical ESP.

Wind turbines are one of the clean ways of generating energy. However this technology hasn't been developed to its full potential yet. There are many turbines installed in a farm, so when the wind goes through the first sets of blades on the first row, some energy will be removed from the wind by the turbines and stored in power storage facilities. Therefore the second row of turbines cant generate power as efficiently as the first row. The wind through the blade generates something called "wake". The wind turbine wake can often be bad for the downstream turbines.

My project was to use CFD (ANSYS) to create a model and analyse the situation. Within this project, different farm layout was proposed. The analyses carried out using CFD delivered a good understanding of the predicted dynamic forces, wind velocity recovery, pressure and so on. These details were valid to estimate an appropriate distance between each turbine to solve the issue of efficiency.

Within this project, I have managed a team of international engineers. We were asked to design a product which can be used to help the people who has been affected by natural disaster and forced to leave their homes and live in refugee camps. The idea was generated from scratch and developed to a full design.

There are currently products on the market that use filters and purification; however these products are limited in their efficiency. Water filters are also widely available; they have the advantages of being able to filter the water and some also have a manual pump attached to them, but viruses in the water would not be removed by these filtration systems. Additionally there are devices which purify and rid the water of the viruses, but the downside to these products is that they would only purify filtered water. There are disadvantages to both products named above. We hope to utilise the benefits of each to provide a complete solution for disaster relief.

WATER PURIFIER STREW

The water purifier was designed using 3 stages. Stage one was sediment pre-filtration to get rid of larger particles, Activated carbon soaked in any viruses in the water in second stage and at the end Hollow Fibre removed any bacteria remained in the water and the output water was tested to be safe. These stages can be observed in figure 5.0. Key Skills: Research, CAD skills, Materials, Marketing

The chemical, military, petroleum or even nuclear power-plant industries often use thick walled cylinders. The FEA based commercial tools such as ABAQUS are available to use, in order to carry out an accurate analysis and design optimization of a thick pressure vessel.

A pressure vessel was designed in this project at first. The stress variations in the pressure vessel and was analysed, 4 different type of cracks was introduced and the result was found. FEA and empirical was the two approaches used. The full analysis was carried out to determine the limit and safe load of the vessel based on Tresca and Von Mises yield criteria.

Key skills: Finite element methods, Mechanic of material and use of ABAQUS

PRESSURE VESSEL

Shopping Carrier bags carrier was designed for people who has skin problem who and are on a long term steroids treatments. Using Pro Engineering the handle shown on the right hand side was designed and manufactured. This item might look so simple, however most of the steps of Computer Aided Design modelling had to be used to manufacture it.

There are number of ways in which computer could aid the designer. These are processes like preforming design calculations, producing and managing parts list, storing and retrieving design information, producing drawings and producing programs for numerically controlled (NC) machine tools. Design calculations and parts list processing where the first applications (Jones 1990). Some of these aids like plastic advisor, mould, and NC were used in designing the reusable carrier bag handle and explained within this project.

Key skills: Pro Engineering, Engineering of material, CNC programming, report writing.

CARRIER BAG CARRIE

Pressurised air can always be put to a good use. The challenge with this project was that we were asked as a group of engineers to design a compressor which the pressure had to be increased but the input power had to decrease. Normally the air rifle pumps in competition are powered by 230V. That means the motor used in the device have a reliable power to fulfil the job quickly. This work involved a design of a very similar device in terms of the task the product had to carry. The requirement for this project was an air pump with the output of 250bar of pressurised air and input of 12V. This product designed to be used in competitions on site so it has to be made portable.

Key skills: Engineering calculation, Solid mechanics, Hydraulics, CAD, Project managements and engineering of material.

AIR COMPRESSOR

Within the team of engineers, we were asked to design a hydraulic trolley jack with a certain specification. This project required a fair amount of knowledge in hydraulics, engineering calculation and CAD modelling. The challenge was the dimensions and the required capacity. It was very difficult to make it in a way that the jack could lift 9 tonnes with limited dimension.

Solidworks was used for the CAD design and CES Edupack was used to carryout the life cycle analysis (LCA)

Key skills: Hydraulic, Engineering Calculations, Solidworks, Engineering of Material

When the average input power required by a vacuum cleaner was 1800W, I have received an individual project to do which required to design an environmental friendly vacuum cleaner. Lots of research went into this project and the outcome found was that the suction power generated by many of these famous brands was so much more than a vacuum cleaner required to clean a surface. It was also found that the high suction power will damage the surface of high valued carpets. After a very detailed research the conclusion was that only 80W of input power was required to run an eco friendly vacuum cleaner which almost has the same outcome to the 1800W inputted vacuum cleaners. There are now many of these eco vacuum cleaners available in the market which work with internal chargeable batteries.
