The main purpose of this research is to find a mathematical model for the braking torque of auxiliary hydrodynamic brake in drilling rig linking some of operational parameters which are the pressure in brake chamber, density and viscosity of operating liquid inside the brake, we can use this model to know the value of braking torque directly with any changing in this parameters.
The laboratory tests show the effect of any parameter independently, after that and by using of inverse analysis method we suggest a mathematical model which it take in consideration the combined effect for this parameters on braking torque of hydrodynamic brake.
The suggested model is the result of the experimental conditions so we developed this model to simulate the field conditions.
