I am simulating injector nozzel to see cavitations and want to validate Winklhofer results using Mohan's paper(attached in files). I simulated flow for simple geometry (attached in files) with sharp edge and validated the resultes successfuly, when i made little change in geometry 20 micro meter round edge at throat of nozzel, results changed drastically and vapors vanished even with same boundary condition and flow modle. Can any one help me in solving this?
