Abstract

The effect of pressure of the gas-coolant heat exchanger of the regenerative checker is investigated. It is shown that increasing the gas pressure coolant leads to intensification of heat exchange between the gas and the checker. With the use of similarity theory, physical and mathematical modeling of the expediency of increasing the gas pressure in the coolantregenerative real heat exchangers in particular blast heater was explained.
