Heat Flux Measurements from a Human Forearm under Natural Convection and Isothermal Jets
This work is an experimental study on heat transfer from a human arm and a model cylinder. Heat transfer from a human forearm to a large jet, representative of a building HVAC vent/outlet was studied using both an IR camera and a heat flux sensor. The isothermal jet was discharged horizontally from …

A Novel Thermal Method for Pipe Flow Measurements Using a Non-invasive BTU Meter
… a sensor-based apparatus--"namely, the Combined Heat Flux and Temperature Sensor (CHFT+), which employs simultaneous heat flux and temperature measurements for non-invasive thermal interrogation (NITI). In this work, the CHFT+ sensor embodiment is referred to as the British Thermal Unit (BTU) …

Steady State Mathematical Modeling of Non-Conventional Loop Heat Pipes: A Parametric and a Design Approach
A Non-Conventional Loop Heat Pipe, much different from a conventional LHP, is employed in cooling Light Emitting Diode luminaries in high bay lighting. Different from a conventional LHP, these devices use the entrainment phenomenon to passively transport waste thermal energy dissipated from the …

Electrohydrodynamic Microfabricated Ionic Wind Pumps for Electronics Cooling Applications
… on the collector electrodes enhances the overall heat transfer coefficient and facilitates an IC compatible and batch process. The main purpose of the work presented here is thus to investigate whether an optimized ionic wind pump employed in an array configuration might exhibit performance …

Development of high efficiency high speed permanent magnet generator
… these machines produce a substantial amount of heat. This makes the thermal management of these machines difficult and complicated, which leads to demagnetization and the reduction of the output power and shortens the lifetime of the critical components such as the bearings. This thesis presents …
