Flow Simulation over a cylinder at different Reynolds number: Solidworks CFD Tutorial

Aim : To simulate flow over a cylinder at different Reynolds number. Run a baseline simulation and then calculate the Reynolds number. Introduction : The present study to analyse the fluid flow over a cylinder and calculate Reynold's number for baseline simulation and increase the calculated Reynolds number to a factor of 20%, 40%, & 100% and perform the simulation for all the three values of Reynold's number and create an animation file for velocity-pressure. Parameters : Cylinder Diameter : 0.06m Cylinder Length : 0.120m Baseline Velocity : 10 m/s Working Fluid : Air Density of Working Fluid : 1.225 kg/m3 Dynamic Viscosity of Working Fluid : 1.81 × 10-5 kg/(m.s) Length of Domain : 0.21 + 1.29 = 1.5m Flow Through Time : Length of Domain / Inlet Velocity of Fluid End Time = 2 * Flow Through Time (Recommended) CONCLUSION(OBSERVATION) • As Reynold's number increases the Velocity increases and the flow through time decreases. • As the velocity or Reynold’s number increase the flow over the cylinder becomes steady and the velocity plot at 20% and 40% exhibit slight unsteady plot whereas at 100% the flow is steady and we can draw a clear understanding of the flow when velocity is increased. • There is no significant change in the pressure plot and pressure is mainly acting of the frontal area of the cylinder. #solidworks_flow_simulation #solidworks_flow_simulation_tutorial #solidworks_flow_simulation_tutorial_beginner #solidworks_flow_simulation_heat_transfer #solidworks_flow_simulation_nozzle #solidworks_flow_simulation_airfoil #ki #solidworks_flow_simulation_volve #solidworks #flow_simularion Like - Share - Subscribe
