Adiabatic Packed Column Supercritical Fluid Chromatography
… decrease in chromatographic performance at temperatures above 40 C and outlet pressures below 120 bar. This phenomenon has been attributed to isenthalpic expansion and cooling of the mobile phase and poor heat transport under these temperatures and pressures. If the temperature of the fluid …

Experimental study of natural convection heat transfer and gaseous dynamics from dual-channel circulation loop
… a component or region of the prismatic very high-temperature reactor (VHTR) such as plenum-to-plenum heat transfer and gaseous dynamics during natural circulation. Natural circulation of the coolant is the leading capability for VHTR to transport the decay heat from the core to the reactor vessel …

The role of the thermal contact conductance in the interpretation of laser flash data in fiber-reinforced composites
… method results to be meaningful a homogeneous temperature front must exist at the back face of the sample, where the measurements are made. In this work, the parameters that render the radial temperature response of a fiber reinforced composite homogeneous at the back face were investigated. …

Laminar heat transfer to non-Newtonian fluids in pipes with abrupt changes in diameter
… upstream and downstream tube sections heated. Radial temperature traverses were also under taken primarily to justify the procedures used in estimating the tube wall and bulk fluid temperatures and secondly to give further insight into the mechanism of heat transfer beyond a sudden tube …

Investigating temperature distributions and thermal conduction effects in laser-heated plasmas relevant to Magnetized Liner Inertial Fusion
… of the spatially resolved spectra recovered temperature distributions Te(z) that are resolved along the direction of laser propagation but spatially integrated along the instrument's line-of-sight [1]. These temperature profiles can be used to assess how different experimental parameters such …

Study to characterise the performance of micro tubular solid oxide fuel cells by the invention of an avant garde experimental apparatus and computational modelling.
… fuel utilisation, I/V curves and external cell temperature profiles. All of the above multi physical phenomena match very well to the experimental results. A key finding of the thesis is the importance of including radiation equations in the CFD models. Neglecting radiation can result in …

Resonant wave-ion interactions in the heliosphere: I. Interplanetary traveling shocks, II. Ion heating and acceleration in the extended corona
… observed in the extended corona: anisotropic temperature distributions, and differential streaming between protons and minor ion species. However, we fail to model the observed radial temperature dependence of protons and O5+ ions.</p>

Design of a high pressure flow reactor for gas phase kinetics
… to study fuels in engine like conditions (high temperatures, pressures, and fast residence times). This desire to study fuels at such extreme conditions stems from the need for well validated Reaction Mechanisms for use in engine modeling to improve on fuel efficiency and energy output. Original …

Transport Properties of Divertor Edge Plasmas Measured with Multi-Spectral Imaging
… poloidal flux expansion is expected to lower the temperature of the divertor target by increasing the plasma volume and connection length of the magnetic field line between the core and target. These benefits are observed in the conduction limited regime but not in the partially detached regime. …

A theoretical analysis of the temperature response in a bimetallic, composite geometry, nuclear reactor pressure vessel undergoing a loss-of-coolant accident
… two-dimensional analysis indicates that maximum temperatures do not necessarily occur at the outer insulated boundary of the pressure vessel. The results of this analysis are verified by numerical techniques and are used as the initial conditions for the two-dimensional, transient analysis that …

Melt growth of BSO (Bi₁₂SiO₂₀) : critical issues for growth in a micro-g environment
… distribution and the stability of the axial and radial thermal profile within the charge, are critical for the establishment of desirable growth environment (Chap 4 ). In this phase of study, the thermal characterization of a modified vertical Bridgman system for growth of BSO were conducted by …

CFD studies of complex fluid flows in pipes
… of transversal vibration on heat transfer and temperature uniformity in Newtonian and non-Newtonian shear thinning fluids. Vibration was found to generate sufficient chaotic fluid motion that led to considerable radial mixing which translated into a large enhancement in wall heat transfer as …
