Performance of a dehumidifying compression heat pump with auxiliary heat input
Heat Recovery Systems and CHP, 1992Abstract Experiments are carried out on a R114 dehumidifying heat pump installed in a closed circuit drying tunnel. The influence of auxiliary heat input before condenser and/or evaporator are studied. Actual coefficient of performance varied from about 2 to 3. Studies throw light on the significance of the location of the auxiliary heat input in the

Transient Analysis of Nonuniform Heat Input Propagation Through a Heat Sink Base
Journal of Electronic Packaging, 2016For thermal management architectures wherein the heat sink is embedded close to a dynamic heat source, nonuniformities may propagate through the heat sink base to the coolant. Available transient models predict the effective heat spreading resistance to calculate chip temperature rise, or simplify to a representative axisymmetric geometry.

Heat input properties of hollow cathode arc as a welding heat source
Journal of Physics D: Applied Physics, 2005In order to clarify whether a hollow cathode arc (HCA) can be used as a welding heat source in space, investigations into the fundamental characteristics of HCA were experimentally performed under low pressure conditions. The HCA method enables an arc discharge to ignite and maintain under low pressure conditions; in contrast, low pressure conditions ...
