Re: water hammer
HI iam working in modleling waterhammer ,and in order to study the water hamer in pipeline using fluent the follwoing steps should be used,fluent 6.2 vertion should be used with 3ddp,segregate solver,the density should be set as a udf ,then the panal for speed of sound get can begin with steady solver initialy with the open valve then the case should run in a unsteady solver. if you have any idea about how can i get oscillation values of pressure and velocity at several monitoring points during the calculation please tall me . moutazz
