Coupled Heat Transfer Processes in Enclosed Horizontal Heat Generating Rod Bundles
(2018-03-24)In a nuclear fuel cask, the heat generating spent fuel rods are packed in a housing and the resulting bundle is placed inside a cask of thick outer shell made of materials like lead or concrete. The cask presents a wide ... -
A Design Concept of a Volumetric Solar Receiver for Supercritical CO2 Brayton Cycle
(2018-01-09)Recently, the supercritical carbon dioxide (s-CO2) Brayton cycle has been identified as a promising candidate for solar-thermal energy conversion due to its potentially high thermal efficiency (50%, for turbine inlet ... -

Hybrid Model for Micro-channel Heat Exchangers used in sCO2 Brayton Power Blocks
Studies have shown that Micro-channel Heat Exchangers (MCHEs) commonly referred to as Printed Circuit Heat Exchangers (PCHEs) are suitable candidates for recuperators and gas coolers used in sCO2 power blocks. CFD and 1-d ... -
Investigations On Film Cooling At Hypersonic Mach Number Using Forward Facing Injection From Micro-Jet Array
(2010-07-16)A body in a hypersonic flow field will experience very high heating especially during re-entry. Conventionally this problem is tackled to some extent by the use of large angle blunt cones. At the cost of increased drag, ... -
Momentum And Enthalpy Transfer In Packed Beds - Experimental Evaluation For Unsteady Inlet Temperature At High Reynolds Numbers
(2013-06-10)Solid propellant gas generators that have high gas capacity are used for fast pressurization of inflatable devices or elastic shells. However, many applications such as control surface actuation, air bottle pressurization ... -
Nonlocal continuum models for plasticity and damage
Nonlocal interactions of material points play a vital role in modelling certain important aspects of inelastic phenomena such as plasticity and damage in solids. For plasticity problems, nonlocal interactions allow ... -
Numerical Study Of Heat Transfer From Pin Fin Heat Sink Using Steady And Pulsated Impinging Jets
(2008-01-25)The work reported in this thesis is an attempt to enhance heat transfer in electronic devices with the use of impinging air jets on pin-finned heat sinks. The cooling per-formance of electronic devices has attracted increased ... -
Numerical Study Of Laminar And Turbulent Mixed Convection In Enclosures With Heat Generating Components
(2010-07-29)The problem of laminar and turbulent conjugate mixed convection flow and heat transfer in shallow enclosures with a series of block-like heat generating components is studied numerically for a Reynolds number range of zero ... -
Numerical Study Of Low Mach Number Conjugate Natural Convection And Radiation In A Vertical Annulus
(2010-07-23)The problem of low Mach number (non-Boussin´esq) conjugate laminar natural convection combined with surface radiation in a vertical annulus with a centrally located vertical heat generating rod is studied numerically, ... -
Role Of Mixed Convection In Cooling Of Electronics
(2011-03-15)Cooling of electronic components is one of the most important issues concerned in the electronic industry for design of equipment. Maintaining the temperature of an electronic device within its safe operating temperature ... -
Shock Tunnel Investigations On Hypersonic Separated Flows
(2009-08-11)Knowledge of flow separation is very essential for proper understanding of both external and internal aerothermodynamics of bodies. Because of unique flow features such as thick boundary layers, merged shock layers, strong ... -
Turbulent Free Convection Over Horizontal Surfaces
This thesis deals with turbulent free convection in a horizontal fluid layer above a heated surface. The work can be roughly divided into two parts. In the &st part a model is proposed for the near wall dynamics in ...
