Dynamic analysis of air flow over Iranian National Observatory (INO) site (Mount Gargash): Analysis of convective flow and thermal plume over optical telescopes

A lot of factors play role when deciding the location of a new telescopic site. One of the most important of these factors is the "Seeing" parameter which is a measure of the extent the earths atmosphere distorts the images from the space. Locations are chosen based on an average value but localized and short-term atmospheric phenomena could have greater effect on image distortion than the year round average. Astronomers must be aware of these changes, so that they can compensate for them. My project analyzes the convective flow over the mount Gargash (INO's location) due to temperature difference between mountain surface and atmosphere. During the day, sun warms up both the mountain and the air above it, but air loses this heat more quickly, therefore a temperature difference between the surface and atmosphere is created. This project is an extension of my thesis.

Analysis of flow past a golf ball and a smooth ball: Comparison with experimental data, analysis on coefficient of drag, assessment of K-ε model

The dimples on the surface of a golf ball, cause the flow over it to become turbulent and hence the coefficient of drag reduces, compared to a smooth ball. Here the goal was to find out about the accuracy of K-ε model by analyzing both a golf ball and a smooth ball.

Conversion of a commercially available gas-powered car to a plug-in hybrid (competing at Iranian Machine Design Competition)

Iranian Machine Design Competition (IMDC-www.imdc.ir) is annual competition, held among all universities across the country. Its goal is to promote team work and green motoring. During the 3rd of the competition, I was the manager for one of the competing team. Our team successfully passed the "Conceptual Design" and "Detail Design" phases but unfortunately, due to lack of funding, we were not able to build our vehicle and were forced to pull out of the competition altogether. Here are some of the tasks preformed during this project:

- Vehicle performance assessment (converting a standard vehicle to a hybrid)
- Vehicle vibration analysis
- Vehicle structural analysis using ANSYS Workbench
- Brake system design
- Vehicle dynamics assessment (ride, handling, etc.)
