Developing next generation transient heat exchangers is a transformative technology for efficient ther-mal management of advanced power electronics and electric machines (APEEM) inside hybrid electric,electric, and fuel cell vehicles as well as renewable energies (wind, solar, tidal). Optimal design criteriafor such dynamic heat exchangers should be achieved through addressing inter...

We prove Gaussian estimates for heat kernels on semisimple Lie groups by using the method of Bloch wave representation. We also give a large time asymptotic expansion for heat kernels on compact extensions of abelian Lie groups.

A set of closed form equations for the preliminary evaluation and design of a heatpipe-cooled leading edge is presented. The set of equations can provide a leading-edge designer with a quick evaluation of the feasibility of using heat-pipe cooling. The heat pipes can be embedded in a metallic or composite structure. The maximum heat flux, total integrated heat load, and thermal properties of th...

The pulsating heat pipe is a very promising dissipation device to address the challenge of higher heat-flux electronic chips, as it characterised by excellent transfer ability and flexibility for miniaturisation. To boost application PHP, reliable performance evaluation models are especially important. In this paper, correlation was firstly proposed closed PHP with various working fluids (water...
