Heat transfer characteristics of heat storage type heat transfer element for gas turbine.
TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series B, 1990 Many papers have described heat transfer in a regenerator core. We tried to obtain an approximate solution of original partial differential equations dealing with heat transfer between gas and core. The exact solution of the original equations is so complicated that the equations were converted to simultaneous ordinary differential equations by using ...

Heat-Transfer Characteristics in Screen-Wick Heat Pipes
JSME international journal. Ser. 2, Fluids engineering, heat transfer, power, combustion, thermophysical properties, 1987 Heat transfer coefficients and maximum heat transfer rates due to capillary limitation were investigated in horizontal heat pipes with stainless-steel screen-wicks, using water as a working fluid. The heat transfer coefficients in a condenser can be estimated by the equation of heat transfer across the liquid-saturated wick.

Heat transfer characteristics of in-ground heat exchangers
International Journal of Energy Research, 1983 Most in-ground heat storage installations use a system of horizontal or vertical plastic pipes to carry heat exchanger fluid. In designing these systems it is generally assumed that the thermal effects of the plastic pipe can be neglected. This paper reports a laboratory study of the pattern of heat flow around fluid-carrying plastic pipe buried in ...
