Microfluidic Investigation of Tracer Dye Diffusion in Alumina Nanofluids
(2012-10-05)
Nanofluids, a new class of fluids engineered by suspending nanometer-sized particles in a host liquid, are offered as a new strategy in order to improve heat and mass transfer efficiency. My research was motivated by ...
Modeling of LNG Pool Spreading and Vaporization
(2012-11-20)
In this work, a source term model for estimating the rate of spreading and vaporization of LNG on land and sea is introduced. The model takes into account the composition changes of the boiling mixture, the varying ...
Heat Transfer in Smooth and Ribbed Rectangular Two-Pass Channels with a Developing Flow Entrance at High Rotation Numbers
(2010-01-16)
Cooling channels with a developing flow entrance condition and aspect ratios of
1:4 and 2:1 were studied. The range of the rotation number and buoyancy parameter for
the selected AR channels was extended. The maximum Ro ...
Film cooling effectiveness measurements on rotating and non-rotating turbine components
(Texas A&M University, 2007-04-25)
Detailed film cooling effectiveness distributions were measured on the stationary
blade tip and on the leading edge region of a rotating blade using a Pressure Sensitive
Paint technique. Air and nitrogen gas were used as ...
Study of the Effects of Single and Double Droplets Impingement on Surface Cooling
(2012-10-19)
Spray cooling is a promising technique which is used to remove large amounts of heat from surfaces. It is characterized by uniform heat removal, low droplet impact velocity and better cooling efficiency when compared to ...
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 ...
Flow and Heat Transfer Characteristics of Microencapsulated Phase Change Material Slurry in a Coil Heat Exchanger
(2015-10-05)
The use of enhanced heat transfer fluid and heat exchanger can improve the performance of thermal energy systems. Microencapsulated phase change material (MPCM) slurry is considered as an enhanced heat transfer fluid and ...
Characterizing Early Frost Formation on Vertical Surfaces Under Forced Convection
(2020-01-08)
This investigation characterized early frost formation by quantifying the velocity of the aggregate freezing front and examining the underlying factors that have a direct effect on it. The experiments were carried out under ...
Multiscale Transient Thermomechanics of Heterogeneous Materials
(2020-04-21)
Here, a number of analytic and computational models are utilized to study the transient thermomechanical response of heterogeneous materials. The models account for thermal stresses generated by incompatibilities in thermal ...
Towards the Improvement of Common RANS Models in the Prediction of Buoyancy Influenced Heated Gas Flows
(2020-07-08)
An emerging trend in the nuclear community is to utilize RANS based turbulence models to supplement thermal-hydraulic system codes in the design of Generation-IV (Gen-IV) power reactors. Prior to full integration into the ...
