The Pressure Drop for Laminar Flow in 3D Straight and Elbow Pipes Using Computational Fluid Dynamics

Abstrak

Designing piping systems for laminar flow requires an understanding of pressure drop. Pressure drop can offer insights for selecting pipe materials, designing an efficient piping system, and choosing the appropriate elbows and fittings. Utilizing numerical simulations, the pressure drop in straight pipes, 45^o bends, 90^o bends, and 180^o bends is examined. Velocity profiles for straight pipes and bends are compared, revealing the increase in pressure drop caused by the bend in comparison to the straight pipe. The numerical simulation results indicate that the bend results in an increased pressure drop in the pipe's flow.
