The oscillation of scaled residuals is very big

My settings is as follows:
Models: MixtureRealizable k-eStandard Wall Functions
General: Pressure-Based Transient
Phases: Drag coefficient——Schiller-naumann
Surface Tension——0.072N/m
Boundary Conditions: gas_inlet: velocity_inlet:
outlet: Pressure_out
Solution MethodPISO
every time step the result is converged, but the oscillation of scaled residuals for k and epsilon are very big,I don't know how to solve the problem.
Thank you very much for your help.
