HVAC System Design

Indoor Conditions Control

As a Graduate Engineer designed, sized and laid out a heating and cooling system for a building consisting of a small restaurant, lounge and a kitchen for maximum occupancy of 50 people. Addressing all key elements of a HVAC system namely; load calculation, duct design, selection of equipment, energy efficiency and sustainability analyses.

Tire Hydroplaning

Lab Model & Theoretical Analysis

This project addressed the analysis of the hydroplaning on lab model. Hydroplaning occurs when a tire loses grip, contacts the water, which creates the pressure sufficient enough to lift the tire from the pavement. The main objective was to recreate the effect of hydroplaning in the laboratory environment.

Supersonic Jet

Impulsively Starting Jet Simulation

Constructed a simulation model to examine the evolution of a shock wave. A stationary plate was placed downstream of an impulsively starting under-expanded subsonic/supersonic jet after it comes out of a nozzle into ambient conditions. The results obtained from the numerical method helped aid the understanding of the flow characteristics that accompany the flow when it is initialized, exits the nozzle, reflects on the stationary plate then diverges away from the plate and dissipates as it propagates.

Solar Roof Pod

Solar Decathlon: Team New York

Participated in the “Solar Decathlon: Team New York” in Washington DC. As part of the Mechanical Engineering team, during this project, I collaborated with several teams, developed a great understanding of project management, and enhanced my communication skills. Was able to better understand team work, and how it is based on initiative, problem-solving, adaptability and high standards to successfully achieve goals. Overall I was able to further understand the field of Solar Engineering while gaining hands on experience.

Below are just a few samples of the successful projects I was part of, though some were a sole effort. Each had its own character and challenges, and I'm proud of the results that were achieved.
