Projects and research

In my research, I focus primarily on experimental and computational modeling of thermal fluids and renewable energy problems. Among my interests are enhancing heating , electric arc plasma simulation, simulation multiphase flows, improving transport in porous media , design of thermal systems. Research of this type can be applied to a wide range of scientific and engineering problems. In the field of mechanical engineering, I am open to collaborations with researchers in other countries. I greatly benefit from the interactions between mechanical engineering and applied energy, both as a source of interesting problems and to keep up with new methods and applications. Below is a very brief description of my main research areas:

Sample project: (Industrial project).

Design of high efficiency Aggregate Air Cooling System in production of high efficiency massive concrete structures.

The reduction temperature of aggregate is necessary in production of high efficiency massive concrete structures. The problem was that in the desert regions the high temperature aggregate can develop cracks inside the structure due to the thermal stress thanks to the chemical reaction between water and cement or hydration chemical reaction. This study focuses ondesign a continuous aggregate cooling system using cooled air. The developed design can decrease the temperature of 1 ton of small grain size aggregate from the 30 to 2 oC in 2 minute. The developed system can save both the time and energy by moving the cold air inside the gaps between the stones which have different diameter in the range 10-40 mm. The designed refrigeration cycle utilized multi-stage cooling coils that can decrease the temperature of the cooling air. The design includesparallel semi-hermetic compressors to increase the R22 refrigerant volumetric flow rate and enough to cool the circulated air inside the aggregates layers.

Sample project: Numerical prediction of a bi-directional micro thermal flow sensor

This study aims at developing a numerical analysis of unsteady flow around a micro hot-wire anemometer (HWA) using three parallel wires. Two dimensional numerical models were built and simulated using the diameter of the heated wire to be triple of the sensor wire and with (The separation distance between the heated wire and sensor wire/ The diameter of the heated wire) ratios between . The results are rewritten as a function of Peclet number (time of convection/time of diffusion). It was found that as the ratio increases, the sensitivity of (HWA) device to the time of flight decreases, but the reading of the time of flight becomes more accurate, because the effects of the diffusion and wake after the heated wire decrease. For instance, when at Peclet number =140 the sensitivity of the time of flight goes to zero with an uncertainty of . For the uncertainty of the device to the time of flight exceeds and the readings are unreliable. Moreover, the sensitivity in this region is high, as the diffusion governs heat and fluid flow more than the convection. The frequency of the sending temperature is selected to prevent interface among the temperature responses.

Sample project: Arc Movement inside an AC/DC Circuit Breaker Working with a Novel Method of Arc Guiding

(Developing a new patent for Schaltbau company in munch , Germany)

This project aims at understanding the design concept and behavior of the ionized gases inside a new electrical contactor. The switching device is designed for ac and dc operations up to 3.5 kV and nominal currents up to 800 A. The contactor consists of five electrodes: two anodes, two cathodes, and a moving electrode or bridge which works as an anode and a cathode simultaneously. In order to increase the safety, the electrical contactor includes two contact points. The line current can be diverted into an arc between the electrode and the bridge and an arc between the runner electrodes. The movement of the ionized gases is controlled by two permanentmagnets and two coils installed near the electrodes. The arc plasma itself feeds the coils with current. The arc plasma velocity increases if more current is allocated in the arc plasma. The dynamics of ionized gases in the contactor is analyzed using two optical methods, viz., optical imaging method and high-speed camera (HSC). The optical imaging software has been developed to generate dynamic images of the high-speed ionized gases at a rate of 50 000 frames/s. The results of this method have been compared with those obtained using an HSC. A transient numerical model has been developed to simulate the arc plasma inside the main runner for the case of dc current. The properties of the air plasma are considered variable with temperature and pressure. The calculation shows the position and temperature of the arc plasma as a function of time.
