Thermal Gradients in Southwestern United States and the Effect on Bridge Bearing Loads
… design. This study consisted of two parts, heat flow analysis using long-term meteorological data and two case study bridges in Nevada analyzed for bearing loadings including several variations of thermal gradient loading. One bridge was a two-span concrete posttensioned box girder bridge in …

Mold, flow, and economic considerations in high temperature precision casting
… to produce defect free castings. Here fluid flow, heat flow, and chemical interactions were investigated with simulations and casting experiments. Three mold recipes were developed; an improved magnesium-phosphate binder silica sand based system, a magnesium-aluminum phosphate binder alumina …

Oxidational wear of low alloy steel in gases other than air
… and contact temperatures as determined from heat flow analysis. Unlubricated wear debris was found to be a mixture of αFe2O3, Fe3O4 and FeO oxide. A model has been proposed for tribo-oxide growth demonstrating the importance of diffusion rate and oxygen partial pressure, in the oxidation …

Gallium lanthanum sulphide glasses for near-infrared photonic applications
… and commissioned and an improved model for the heat flow analysis of laser calorimetry was also developed. Our measurements identified optical absorption as the principal near-IR loss mechanism for GLS glasses. The extrinsic absorption due to transition metal ion impurities was also measured, …

The numerical modelling of composite floors exposed to fire
… material properties into account. The method of analysis comprises two parts; the first is thermal analysis, enabling temperatures to be calculated as a fu~ction 'of fire exposure time. The second is strength analysis for calculating the strength of composite floor with material properties …

The mechanics of valve cooling in internal-combustion engines. Investigation into the effect of VSI on the heat flow from valves towards the cooling jacket.
… of valve train components. The majority of the heat outflow from the valve takes place along the valve-seat-cylinder head-coolant thermal path which is significantly influenced by the thermal contact resistance (TCR) present at the valve/seat and seat/head interfaces. A test rig facility and …
