Particle Relaxation Time
Hello, what is the signification of particle relaxation time in multiphase flows? Can you give me reference to read more about it? Kind regards, Chouki

Re: Particle Relaxation Time
Tau_p= typical time for a particle response in a flow. If starting from rest, it takes tau_p for a particle to reach (1-1/e) of the fluid velocity.
tau_p= (particle density)*(particle diameter)^2 over (18*fluid molecular viscosity) Check: Hinds: aerosol technology Abdel |
Re: Particle Relaxation Time
Thank you very much but what do you mean by e (e=2.718282)? Regards, Chouki
