This work deals with an experimental inv estigation of the conv ectiv e heat transfer and pressu re loss in a rectangular channel with discrete flush-mounted and protruding heat sources. Six protruding obstacle heights, which represen t the range of the dimensionless protrusion of 0 F h r H F 0.805, are studied in this work. The temperatures on the heater surfaces and that of the fluid are coll...

This work is focused on exploring the flow and heat transfer capabilities for slotted axisymmetric cavity configurations synthetic impinging jets; jet enclosed between two isothermal parallel plates, into top hot plate. Numerical simulations using Arbitrary Lagrangian-Eulerian formulation of Navier-Stokes equations are performed Reynolds numbers 50, 300 500 a formation criteria 3. The pattern f...

The power dissipation levels in high performance personal computers continue to increase rapidly while the silicon die temperature requirements remain unchanged or have been lowered. Advanced air cooling solutions for the major heat sources such as CPU and GPU modules use heat pipes and high flow rate fans to manage the heat load at the expense of significant increases in the sound power emitte...

This paper reviews materials for thermoelectric waste heat recovery, and discusses selected industrial and distributed waste heat sources as well as recovery methods that are currently applied. Thermoelectric properties, especially electrical conductivity, thermopower, thermal conductivity and the thermoelectric figures of merit, are considered when evaluating thermoelectric materials for waste...

Low-grade heat from sources below 100 C o ers a vast quantity of energy. The ability to extract this energy, however, is limited with existing technologies as they are not well-suited to harvest energy from sources with variable heat output or with a small temperature di erence between the source and the environment. Here, we present a process for extracting energy from low-grade heat sources u...
