It's better to bury the RRF body into the way and define any walls that it crosses as Stators (in the Wall boundary condition). The Electronics Cooling Module add-in enhances Flow Simulations abilities to simulate electronics cooling in several different cases making setting up an electronics cooling flow simulation easier on the user. If you are performing an internal calculation with a RRF, then best practice is to still extend the RRF body beyond the rotating impeller, even if it goes into the solid housing around it. SOLIDWORKS Flow Simulation is very good at simulating the cooling scenarios of electronic equipment on its own. I also typically recommend to define a volumetric mesh control using the RRF cylinder for these solutions. Thus having a few (say 2-3) computational cells between the rotating impeller body and the diameter of the rotating RF cylinder is of utmost importance. The idea here is that you are solving the RRF separately from the global (rectangular) computational domain and the solver needs to transfer information back and forth.
Thust would come from Force surface goal.īecause you are solving this problem using a rotating reference frame (RRF) approach, then in Step 2, you should make the cylindrical sketch (representing the RRF) slightly larger than the rotating propeller. Once again, Best thrust with less torque is the best choice. Take the best result from above and define a new parametric study.įix speed of advance (-Vz) and check a range of RPM around the required one. The goal is to overcome the hull drag, with the minimum required torque. If Solidworks can undertake the simulations you need, and provide a valid result, then I wouldnt call it poor. The likes of Fluent, StarCCM+, OpenFOAM etc have very many models which make them ideal to undertake very complex analysis. Modeling Unsteady Compressible Flow Introduction In this tutorial, FLUENT s. Then, with fixed RPM, a range of fluid speeds around the required Ship speed, must be studied(-Vz in this model). Perhaps Solidworks is FEM based too In which case the FEM/FVM for CFD arguments come in. SOLIDWORKS Flow Simulation Options SOLIDWORKS Flow Simulation includes an. Īs first step, an initial guess of the ship service speed, propeller RPM and hull drag must be known. ME469B/3/GI 5 Why turbulent flows are challenging Unsteady aperiodic motion Fluid properties. In quite a rough way the thing would go as follows. Turbulent Flow Laminar Flow Turbulent Flow The flow is dominated by the object shape and dimension (large scale) and by the motion and evolution of small eddies (small scales) Challenging to compute The flow is dominated by the object shape and dimension (large scale) Easy to compute.
It means that flow motion, thrust and torque are going to be computed for the "static" propeller condition which for most cases is not practical.įor a real analisys, a parametric study would be the way to go. As an example, take this air-water heat exchanger from SOLIDWORKS Flow Simulation tutorial B3 (accessible under Help > SOLIDWORKS Simulation > Flow Simulation Online Tutorial).
