Effectiveness of Drag Reduction Device on Simplified Vehicle Model: A CFD Study

Aerodynamic drag significantly influences vehicle performance and fuel efficiency, making its reduction a key focus in automotive design. This study examines the drag reduction of the simplified Ahmed body model by integrating diffusers at 8° and 10° angles. Using Computational Fluid Dynamics (CFD) simulations, airflow...

Numerical Investigation and Optimization of Heat transfer and ExergyLoss in Geometrically Modified Tube Heat Exchangers Using Nanofluids

This study numerically investigates the thermal and energy performance of double helical and conical coil heat exchangers using CFD simulations under turbulent flow conditions. The analysis focuses on optimizing key design parameters—coil geometry, coil pitch (16 mm and 20 mm), and hot and cold flow rates (1.5 to 6 LPM...
