Research Interests

" Success is not the key to happiness. Happiness is the key to success. If you love what you are doing, you will be successful."

-Albert Schweitzer


Computational Fluid Dynamics

Computational fluid dynamics, usually abbreviated as CFD, is a branch of fluid mechanics that uses numerical analysis and algorithms to solve and analyze problems that involve fluid flows. Computers are used to perform the calculations required to simulate the interaction of liquids and gases with surfaces defined by boundary conditions.


Aerodynamics and Gas Dynamics

Aerodynamics, is a branch of fluid dynamics concerned with studying the motion of air, particularly when it interacts with a solid object, such as an airplane wing. Aerodynamics is a sub-field of fluid dynamics and gas dynamics, and many aspects of aerodynamics theory are common to these fields. The term aerodynamics is often used synonymously with gas dynamics, with the difference being that "gas dynamics" applies to the study of the motion of all gases, not limited to air.


Computational Battery Simulation

The recent interest in the development of environmentally friendly vehicles powered either fully (electric vehicles, EVs) or partially (hybrid electric vehicles, HEVs) by batteries has resulted in enhanced research into various aspects of this electrochemical energy source. These range from the development of better designs to suit the application (e.g. design favoring high power for HEVs while favoring high energy for EVs) to the development of new materials with superior performance. Parallel to various experimental research programs, mathematical models that describe the behavior of batteries and their interaction with other devices in a vehicle have also received much attention. These models range from those that describe the physics of the various phenomena in the cell.


Internal Combustion Engine

An internal combustion engine (ICE) is a heat engine where the combustion of a fuel occurs with an oxidizer (usually air) in a combustion chamber that is an integral part of the working fluid flow circuit. In an internal combustion engine the expansion of the high-temperature and high-pressure gases produced by combustion apply direct force to some component of the engine. The force is applied typically to pistons, turbine blades, or a nozzle. This force moves the component over a distance, transforming chemical energy into useful mechanical energy.

Hybrid Vehicle

A hybrid vehicle uses two or more distinct types of power, such as internal combustion engine+electric motor, e.g. in diesel-electric trains using diesel engines and electricity from overhead lines, and submarines that use diesels when surfaced and batteries when submerged.


Courses

"The thing I loved the most - and still love the most about teaching - is that you can connect with an individual or a group, and see that individual or group exceed their limits."

  • Status and Challenges of Cleaner and Efficient Fuels and Vehicle in Iran

    UNEP is supporting countries to develop cleaner and efficient fuels and vehicles. Two of its main initiatives on this issue are the Partnership for Clean Fuels and Vehicles (PCFV) and the Global Fuel Economy Initiative (GFEI). The PCFV promotes the phase out of lead and the development of fuel quality roadmaps, focusing on phasing down sulfur in fuel, and developing equivalent vehicle emission standards. The GFEI, on the other hand, promotes the development and adoption of efficient vehicle policies, such as having specific CO2 emission standards or fuel consumption limits for new vehicles, fiscal reform favoring more efficient vehicles, including electric vehicles, labeling schemes, and others. In Asia Pacific, UNEP established the Asia Pacific Clean Air Partnership (APCAP) to support the national efforts in addressing air pollution. Iran attended the first session of the APCAP Joint forum held in November 2015 and expressed that air pollution is a priority environmental issue in Iran.
