Essay

With the use of thermal phisics laws a mathematical model of motion and dissipative heating of fluid flow in the flat, round and annular adiabatic channel is built. By the number computations conformities to the regularity of heating and portion of energy that is expended on heating are set. The effective viscosity dependence of Reynolds number is given. A method of size choice and computation of thermal description of dissipative heaters is developed. Experimental researches are conducted on dissipative heater of biogas plant fermenter and vortical dissipative heater of heat generator. A method of number computation of isothermal heater, wich takes into account dependence of viscosity of fluid flow on temperature, is developed.
