Since University of Tabriz mostly offered Heat and Fluid courses in B.Sc., I was somewhat forced to take them, despite my internal passion for Computer Programming, Mechatronics and Robotics. Thermofluids projects usually employ MATLAB, ANSYS Fluent, GAMBIT, ICEM, OpenFOAM, COMSOL, and other relevant software, with most of which I am already familiar.
This Gas Dynamics course project required use of Gambit, Fluent, and a little MATLAB. We analyzed and simulated steady-state flow of hot air through a supersonic convergent-divergent nozzle, and record the pressure and temperature profiles in different occasions with no shock wave, a shock wave at the exit, and where the shock wave is driven further upstream towards the throat. We also analyzed an occasion where there are shock diamonds present. This project was a very useful exercise in CFD, compressible fluid flow, and working with Fluent under various occasions.
This Heat-transfer project was done in teams of three. The rectangular enclosure was designed in GAMBIT and the process was simulated in Fluent. We tried to compare and contrast our results with that of a similar paper, in order to validate our results. The complexity of the simulation increased when introducing nanofluids into the process. The results were satisfactory.
In this Water Supply Systems course project, we were supposed to compile a thorough one-session presentation on the entire water treatment process, from the ocean fresh water to drinking water or mineral water. We presented our findings in the class, and the experience was very enlightening overall. It not only increased my knowledge of treatment processes and stages, from pumping and containment, screening, pH adjustment, neutralizing filters, soda ash injection, acid injection, flocculation and coagulation, to sedimentation. We studied world demographics, water consumption, water crisis, and presented a comparison of conventional and modern membrane-based treatment processes.
This HVAC Systems course project was similar to the one above; we were supposed to conduct a thorough and detailed research into the HVAC systems of public enclosed swimming pools, and their different sections. This project was very enlightening in that it acquainted us with the unspoken and hidden parameters defining the various aspects of the swimming pool HVAC systems, and how some clever connections can be built between the HVAC systems of different sections of a pool in order to save energy and costs. We familiarized ourselves with numerous conventional and modern techniques and technologies for dehumidification and heat exchange of air collected from different parts of a pool.
This project has two sections: in the first section, we were supposed to draw the steady-state heat transfer vector fields of a 2D system with a hot ball. In the second part, we were given a specific geometry with specific conditions, and were supposed to write a program that would use Finite Difference Method to calculate the time it would take for the system to reach a temperature. In order to make the matter more flexible, I deployed the MATLAB codes and made them executable windows applications. The codes for this project can be seen in the Programming Projects section.
