Characterization of thermo-physical properties and forced convective heat transfer of poly-alpha-olefin (PAO) nanofluids.
(2009-05-15)
Colloidal solvents, containing dispersed nanometer (~1-100 nm) sized particles, are categorized as nanofluids. With the growing heat loads in engineering systems that exceed the current technological limits, nanofluids are ...
Cylindrical thermal contact conductance
(Texas A&M University, 2004-09-30)
Thermal contact conductance is highly important in a wide variety of applications, from the cooling of electronic chips to the thermal management of spacecraft. The demand for increased efficiency means that components ...
Effect of rib spacing on heat transfer and friction in a rotating two-pass rectangular (AR=1:2) channel
(Texas A&M University, 2006-10-30)
The research focuses on testing the heat transfer enhancement in a channel for
different spacing of the rib turbulators. Those ribs are put on the surface in the two pass
rectangular channel with an aspect ratio of AR=1:2. ...
Investigations of flow and film cooling on turbine blade edge regions
(Texas A&M University, 2006-10-30)
The inlet temperature of modern gas turbine engines has been increased to achieve higher thermal
efficiency and increased output. The blade edge regions, including the blade tip, the leading edge, and the
platform, are ...
Heat transfer enhancement for turbulent flow through blockages with elongated holes in a rectangular channel
(Texas A&M University, 2007-09-17)
In this thesis, turbulent forced convective heat transfer downstream of blockages
with elongated holes in a rectangular channel was studied.
The rectangular channel has a width-to-height ratio of 12:1. The blockages have
the ...
Design of an Instrumentation System for a Boundary Layer Transition Wing Glove Experiment
(2012-08-23)
Laminar flow control holds major promise for increasing aircraft efficiency and increasing laminar flow over aerodynamic surfaces could decrease drag by up to 30 percent. The Flight Research Lab at Texas A&M University has ...
An experimental investigation of turbine blade heat transfer and turbine blade trailing edge cooling
(Texas A&M University, 2005-02-17)
This experimental study contains two points; part1 turbine blade heat transfer
under low Reynolds number flow conditions, and part 2 trailing edge cooling and
heat transfer. The effect of unsteady wake and free stream ...

(2009-05-15)
Through past research, it is known that carbon nanotubes have the potential of enhancing
the thermal performance of heat transfer fluids. The research is of importance in
electronics cooling, defense, space, transportation ...
An Implementation of Surface-to-Surface, Blackbody Radiation Heat Transfer in a MOOSE Application
(2020-06-04)
Surface-to-surface, blackbody radiation heat transfer is a fundamental phenomena essential in the evaluation of some heat conduction problems. Representing it in digital simulations is of interest in the nuclear power ...
HEAT TRANSFER AND PRESSURE DROP MEASUREMENTS IN LOW ASPECT RATIO CHANNELS WITH CIRCULAR PINS AND STRIP FINS
(2018-07-11)
The heat transfer study of a rectangular duct has become important as it can replicate the channel geometry of the turbine blade or vane in a real engine. The low aspect ratio channel represents trailing edge channel of ...
