Week 3 Challenge : CFD meshing on Turbocharger
>>In this model first we opened the model after that we seen some open surfaces are there and also so many single cone's and triple cone's are there.after that we started to fill that surface one by one.for filling that surface we are using the option called new , in new there are four option to fill the surface.after filling the surface, we checked geometrical errors, it's called as geometry check.after that we got some geomtrical errors like some open surfaces and also single cone's and triple cone's.after that we cleared one by one cone's.whenwe opened the model, the model was entity type, after that we did changed to pid type.after pid type we seen so many overlapped surface is there.after that we deleted overlapped surface.after completion again we checked geometrical errors, then we got some triple cones is there.after that we started to checked that triple cones one by one.then we got some triple cones which will be need and we kept that one like that.after completion of geometrical errors we are going for next step.
>>In this step we started to checked pid , in properties we seen some default pid already assigned.in that default pid we checked one by one. after that we assigned all pid name.then we seen some single cone's is there we did topo, then it's forming a triple cone's. after that we seen three surface joining one point , so that triple cones forming in that point. after that seen one pink color pid overlapped over the brown color pid. in that part,we need that brown color pid , in order to cut that pink color pid we did project over the pink color surface, after that we delete that overlapped surface.after deleting surface we did topo because of single cone's is forming there.so we did topo.after that we seen triple cone's forming there.after pid name assigned we checked one by one pid, in that one some some surface we got opened. then we started to fill that one.after that we started to create new pid for different different location. we created four pid after that we assigned that pid.after asigning the pid we checked one by one if it's opened or closed, then we can go for surface meshing.
>>Before we go for meshing, we given some temporary pid name, we rename that pid.after that for suface meshing we have some target length as per pids. for all outercasing cover,Inlet casing cover,Compressor casing,Turbo casing for target length is 5mm. we did meshing one by one, as per the meshing guide line.then we can go for next smaller meshing length, in impeller we have give 2 mm meshing length,after we did meshed we can go for blade stage-1&2 and shaft rotor 1mm.after we did meshing we got some error between impeller and rotor. that error like some part is going unmeshed due to varous of mesh length.after that we given the target length , mesh length then we remeshed as per the target length.after completing meshing we checked one by one part and also we got smoth meshing.after surface meshing we can go for volumetric meshing.
>>In surface meshing after completing of meshing, we checked is there any ummeshed surface is there or not. after we checked we going for next step for volumetric meshing. in volumetric meshing we have to click on volume after that we got option box then we have to select on that one whole db then we did ok. after that we got volume desk in volume desk ansa had by default eight different different volume. in that one volume like we have to meshed again and some volume like we have to delete, which have not required.where the liquid need to flow we need that volume.after that we checked preview one by one, what ever the volume no need ,we deleted one by one. after deleting we can go for volmetric meshing one by one like smaller one to bigger one.after completing volumetric mesh we got smoth meshing.
[As per given model briefly describe above and bottom i given the snap and model]
