Usama Ali

Motivated Mechanical Engineering graduate with a strong academic background in energy systems, thermodynamics, and renewable technologies. Skilled in energy and exergy analysis, mechanical design, and system optimization, with research experience in Organic Rankine Cycle (ORC) waste heat recovery. Seeking an entry-level role in renewable energy, mechanical design, or energy systems engineering.

Dual Loop Organic Rankine Cycle (ORC) for Waste Heat Recovery from Marine Engines Tor Vergata University.

• Designed and analyzed a two-loop ORC system for waste heat recovery from a 21 MW marine diesel engine.
• Selected Cyclohexane (HTL) and R245fa (LTL) as working fluids.
• Performed energy and exergy analysis using first and second laws of thermodynamics.
• Simulation executed in Microsoft Excel with CoolProp library.
• Achieved ~1.2 MW net power output with 46% exergy efficiency. Dual Loop ORC increased the total output by 5%.

Conducted exergy destruction analysis and proposed optimization strategies for sustainable marine energy.
