CFD Lab SMEC, VIT University Expt. No.: 3 COMPUTATIONAL ANALYSIS OF LAMINAR FLOW THROUGH A PIPE Register Number 16BME0968 Date :10/1/2019 Slot: L49+L50 OBJECTIVE OF THE EXPERIMENT: To simulate the Two dimensional steady state Laminar flow through a pipe of given dimensions. PROBLEM DESCRIPTION: Consider fluid flowing through a circular pipe of constant radius. The pipe diameter D = 0.1 m and length L = 10 m. The inlet velocity Ūz = 1 m/s. Consider the velocity to be constant over the inlet cross-section. The fluid exhausts into the ambient atmosphere which is at a pressure of 1 atm. Take density ρ = 1 kg/ m ³ and the Reynolds number ( Re) based on the pipe diameter is 1000. Calculate the Entrance region length for laminar flow and verify with computational result. Also, plot the following, (L e /d = 0.06 R e ) 1. Pressure contour along the axis 2. Velocity contour along the axis 3. Velocity vector along the axis 4. Velocity Plot at the outlet SOFTWARES USED: 1. ANSYS WORKBENCH / GAMBIT and FLUENT GOVERNING EQUATION: Continuity Equation: u - Momentum: v - Momentum:
