An experimental analysis of heat transfer in coiled tubes
The axial temperature distribution and average heat transfer coefficients were measured for a coiled tube heat exchanger. Water was heated inside the tube under turbulent flow conditions by low pressure steam condensing on the outside. Inside and outside film coefficients were determined at …

A numerical protocol for death-time estimation
A body's axial temperature distribution at death was experimentally demonstrated by the author to predict the postmortem temperature plateau (PMTP), which is known to affect the measured core temperature value and hence death-time estimation. Yet today's methods of death-time estimation apply only …

Laser-induced heating, phase-shift, and damage : measurements and simulations
… The simulation was also used to compute axial temperature for various power levels, beam diameters, and pulse durations. Laser-induced optical pathlength modulation or phase-shift was computed to study the thermal lensing effect. Power and irradiance damage thresholds were calculated for …

CFD analysis of three-dimensional thermalhydraulics flow effects on wall concentration gradient profiles for Lbe loop fittings
… numbers expected around 200,000 and the usual axial temperature profiles which are being characterized in the DELTA loop at LANL. STAR-CD is the simulation package used to make these predictions, which include detailed 3-D velocity, temperature and concentration gradient profiles of the …

An Experimental Conduction Error Calibration Procedure for Cooled Total Temperature Probes
The accurate measurement of total temperature in engine diagnostics is a challenging task which is subject to several sources of error. Conduction error is predominant among these sources since total temperature sensors are embedded into a cooled strut for measurement. This study seeks to …

The acoustic modelling of dissipative elements in automotive exhausts
… Finally, the effects of both mean flow and an axial temperature gradient upon the transmission loss of catalytic converters are examined. The relative influence the catalytic converter exerts sound attenuation, as compared to dissipative silencers, is also discussed.

Development of MiST-IR : multi-spectral infrared thermography
… diagnostic techniques for measuring the 2-D wall temperature distribution or the 2-D phase distribution of the fluid above the surface. These methods make use of infrared thermography, a well developed practice involving the use of a high-speed infrared camera to collect visual data. By analyzing …

Concurrent evaporating spray jets in dilute gas-solid pipe flows
… solids concentration dilution, gas/solids temperature reduction, and gas/solids velocity acceleration. Furthermore, the jet structure is altered by the change of solids loading, jet mass flow rate and initial droplet size distribution. These interactions of gas, solids and evaporating …
