Pressure Losses Analysis in Air Duct Flow Using Computational Fluid Dynamics (CFD)

Abstract

In this paper, hand calculation and computer simulation was used to determine the pressure loses in air duct flow system for velocity of 5m/s, 10m/s, 20m/s and 40m/s and the results were compared to determine their accuracies. Total maximum pressure was recorded at inlet, while least pressure was observed at outlet. The pressure losses for both hand, and computer simulation increased proportionally to the velocity. Also, both pressures lose obtained from the hand calculation and simulation almost maintained the same pattern and direction. But for purpose of accuracy and fast computation, simulation is preferable
