The comparison shows that it is difficult to obtain accurate temperature profile for buried insulated pipe by the FTS method. However, the average temperature and heat loss are more precise and can be used to solve complicated problems by the analytical method.Peng Wang...
Under this background, the simplified numerical heat transfer model between LDVBP and rock-soil layers is established to calculate the temperature rise and heat loss of the chilled water. Comparing the calculated results with the measured data in Wutongzhuang Coal Mine of Hebei province, the error...
A berm-factor expression (which indicates the increase in tank heat loss rate occurring when an in-ground lank is repositioned at a higher Level and bermed) is developed analytically using a simplified heat flow model. The simplification of the two-dimensional heat flow field is described in ...

Data are reported for soil, pipe, soil surface, and air temperatures; heat loss (0.068–0.117 cal cmmin); and soil thermal conductivity (3.61–5.63 mcal [cm sec°C] ). The data are used to evaluate the heat flow theory which is currently being used to predict the land area required ...
When the geometricalproperties reduce to one, the plate-ground thermal resistance can be expressed regardless of plate dimension, dependingonly on temperature distribution given at surface plate and its temperature difference with medium.CNKI热科学学报(英文版)doi:CNKI:SUN:RKXY.0.2009-03-009...

thereby reducing the capacities of a rectifier and a generator.;CONSTITUTION: A foam sheet for connection of underground buried pipes, which is fused on joined ends of two pipe being connected, comprises first and second sheets and an electric heating wire sheet(220) which is arranged between th...
A seasonal heat storage model is developed to describe the steady-state thermal behaviour of the soil regime surrounding large, cylindrical, partially buried heat storage tanks having soil bermed against the above grade portion of the tank wall. The increase in tank heat loss rate occurring when ...
