Abstract
The article considers the hydrodynamic and temperature dependencies of heat and mass transfer in an evaporator-condensing system representing a pulsating heat pipe with a built-in heater used as an evaporator, a vapor condenser, and an electrohydrodynamic pump for forced pumping through of a coolant. The influence of the electric current intensity and voltage on the electrohydrodynamic pump, the applied power, the temperature head, and other factors on the heat transfer has been investigated in order to reveal the physical peculiarities of the processes under investigation and the creation of a background for their calculation. An electric field is used only in the electrohydrodynamic pump, which is situated outside of the evaporator and condenser. The experimental data are treated in the form of “rectified” dependencies having a generalized character between the dependent and governing parameters of the process. The obtained results can be used for in-depth investigations, as well as for the design and fabrication of cooling and compact thermostabilizing electrohydrodynamic devices.
