DEVELOPMENT OF experimental installation and RESEARCHES OF THE HEAT EXCHANGE INTENSIFICATION IN the DISCRETE-ROUGH SURFACE CHANNELS AT LAMINAR flow OF VISCOUS medium
The experimental installation for research of the heat exchange intensification at laminar flow of viscous fluids in the heat power equipment channels is developed. Used are the various periodic discrete-rough surfaces at various charges and temperatures of heat-transfer agent and boundary conditions on channel walls. The work principle of installation is described and the lapse of measuring apparatuses is sized up. The formulas for machining of the experimental researches are resulted, providing definition of integrated characteristics of process: averages on ambit and length of pipes and channels the convective heat exchange and water resistance factors. The actuating mediums there are turbine oil Tp-46 and transformer oil TKP. Results of test researches are shown.
