The influence of the rotor shape on the efficiency of the hydrodynamic heater

Eastern-European Journal of Enterprise Technologies
The paper discusses issues related to the design of a hydrodynamic throttle type heater. The maximum angular velocities for cylindrical and conical shapes are determined from the condition of non-spilling of liquid from a rotating vessel.
