![]() We'll verify the results by following a systematic process which includes comparing the results with the analytical solution in the full-developed region. We'll solve this problem numerically using ANSYS Fluent. Take density ρ = 1 kg/ m 3 and coefficient of viscosity µ = 2 x 10 -3 kg/(m*s). These parameters have been chosen to get a desired Reynolds number of 100 and don't correspond to any real fluid. Laminar flow occurs at lower velocities, below a threshold at which the flow becomes turbulent. The pressure at the pipe outlet is 1 atm. When a fluid is flowing through a closed channel such as a pipe or between two flat plates, either of two types of flow may occur depending on the velocity and viscosity of the fluid: laminar flow or turbulent flow. The pipe diameter D = 0.2 m and length L = 3 m Consider the inlet velocity to be constant over the cross-section and equal to 1 m/s. This module is drawn from MAE 4230/5230 Intermediate Fluid Dynamics at Cornell University.Ĭonsider fluid flowing through a circular pipe of constant radius as illustrated below.
