Abstract: The propulsion and vortical flow of a preswirl pump-jet propulsor (PJP) under effective wake conditions are numerically investigated by improved delayed detached eddy simulation. The numerical results agree well with the ...

Abstract: The gray medium approximation treating all phonons with an averaged and representative mean-free-path (MFP) is an often used method in analyzing ballistic-diffusive heat conduction at nanoscale. However, whether there ...
