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 ...

Characteristics of Heat Transfer for Heat Pipe and Its Correlation [PDF]

ISRN Mechanical Engineering, 2011
In spite of wide application of heat pipe in microelectronics cooling system, a complete understanding of heat pipe mechanism has not yet been completed. An experimental investigation of heat transfer performance of a heat pipe for dry condition and with three different liquids as acetone, methanol, and water having four fill ratios, for each liquid ...

Transient heat transfer characteristics of a heat pipe.

KAGAKU KOGAKU RONBUNSHU, 1987
Transient heat transfer characteristics of a typical heat pipe for which the thermal loading was variable with time were investigated experimentally by using an automatic measuring system. Significant behaviour of step, frequency and pulse responses of surface temperature and heat transferred in particular was observed.

Heat transfer characteristics of NiO nanofluid in heat exchanger [PDF]

AIP Conference Proceedings, 2020
The application heat tranfer process has widely used in several areas of industry, one of regular device that used is heat exchanger that could be found in cooling system, refineries, power plant, etc. The commonly fluids used in heat exchanger were water, minral oil, and ethylene glycol which has poor heat transfer characteristic. Therefore, nanofluid
