Heat transfer from a finned pin to the ambient air
… with pins, no information is available on the heat transfer characteristics of a pin and annular fin combination, i.e., a finned pin. The increased surface area of a finned pin would promote more heat transfer. In this thesis a theoretical investigation of the basic heat transfer …

Optimization of the design of an extended surface with finned pins
… pins have proved to be unique in increasing the rate of heat transfer. Hsieh working on the original idea ot professor Hsu proved that heat transfer rate can be further increased by putting annular fins on a pin. In this thesis the design of finned pin was optimized to give maximum heat transfer …

Two investigations of compressor stability : spike stall inception and transient heat transfer effects
… propagating in the cascade environment at a rate consistent with the low-speed compressor. The cascade design produces high incidence at the mid-span and fast-response velocity measurements show pre-cursor formation away from the tip region. Unsteady computations confirm leading-edge …

Exploring wellbore and reservoir temperature profiles in fluid circulation and production operations
<p>"The wellbore heat flow occurs during different well operations resulting from any temperature differences between the wellbore fluid and the adjacent formation. Understanding the direction and mechanism of heat flow whether it is conduction or convection help to represent this heat exchange …

Thermal sustainability of low-temperature geothermal energy systems: System interactions and environmental impacts.
In storing heat during summer for use in winter, the ground provides a better source/sink of heat than the outside air in regards to heat pump efficiency, being cooler than the outside air in the summer and warmer in the winter. Due to their good efficiency, the use of geothermal energy is often …
