A numerical study of convection in a channel with porous baffles
(Texas A&M University, 2005-02-17)
The effects on heat transfer in a two-dimensional parallel plate channel with sixteen porous baffles in a staggered arrangement with a uniform heat flux heating applied to the top and bottom walls has been numerically ...
Film cooling on a flat plate: investigating density
(2009-05-15)
This study is an investigation of two specific effects on turbine blade film cooling. The
effect of coolant to mainstream density ratio and upstream steps was studied. The
studies were conducted on two flat plates with 4mm ...
Shaped hole effects on film cooling effectiveness and a comparison of multiple effectiveness measurement techniques
(Texas A&M University, 2005-02-17)
This experimental study consists of two parts. For the first part, the film cooling effectiveness for a single row of seven cylindrical holes with a compound angle is measured on a flat surface using five different ...
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. ...
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 ...
An experimental study on the effect of ultrasonication on viscosity and heat transfer performance of aqueous suspensions of multi-walled carbon nanotubes
(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 ...
Determination of heat (mass) transfer from blockages with round and elongated holes in a wide rectangular channel
(Texas A&M University, 2007-04-25)
Mass transfer experiments were conducted to study the thermal performance
characteristics of blockages with round and elongated holes, positioned in a 12:1
rectangular channel. Naphthalene sublimation technique was adopted ...
