On phase-lag Green–Naghdi theory without energy dissipation for electro-thermoelasticity including heat sources

Mechanics based design of structures and machines, 2019
A mathematical model of electro-thermoelasticity has been constructed in the context of a new consideration of heat conduction with phase-lag Green-Naghdi theory without energy dissipation (GN-II).

Heat current limiter and constant heat current source

Physical Review E, 2012
Current limiters and constant current sources, which play important roles in electronic circuits, have been built up for many decades. Their thermal counterparts, heat current limiters and constant heat current sources, are still not available yet. By combining two typical nonlinear lattices, the Frenkel-Kontorova (FK) lattice and a coupled rotator ...

Relativistic moving heat source

International Journal of Heat and Mass Transfer, 2005
Abstract The relativistic heat conduction (RHCE) model is particularly important in the analysis of processes involving moving heat sources (MHS) at speeds or frequencies comparable with those of heat propagation in the medium. This paper establishes a unified framework for solving heat conduction problems using the RHCE model. It offers “Fundamental

Radiant heat gain from indoor heat sources

Heat and Mass Transfer, 2005
A new parameter, equivalent emissivity, ee, is introduced to reflect radiant feature of the surface of a heat source with different shapes and different temperatures in an air conditioned room. Radiant heat gain from medium- or low-surface-temperature equipment and from commonly used light fixtures and the occupant are examined and analyzed in detail ...

Heat transfer enhancement from protruding heat sources using perforated zone between the heat sources

Applied Thermal Engineering, 2009
Abstract This study is to experimentally investigate the heat transfer enhancement by perforation in air cooling of two in-line rectangular heat sources module. Two separation distances between the heat sources were investigated at s/L = 0.5 and 1.0. The area between the heat sources in both cases were perforated in aligned arrangement such that the ...

SP-100 Heat Source Heat Exchanger Design

AIP Conference Proceedings, 1994
A conceptual design for a liquid metal to gas counterflow heat exchanger has been developed for use in the SP‐100 Closed Brayton Cycle (CBC) Space Reactor Power System (SRPS). The Heat Source Heat Exchanger (HSHX) is required to transfer 80 kWt from the 1350 K lithium reactor coolant to the He/Xe working fluid of the Brayton Rotating Unit (BRU).
