Natural convection from a horizontal heater in response to steady and pulsatile input powers
(Monterey, California. Naval Postgraduate School, 1992-06)
Natural convection heat transfer from a flush mounted heater on a larger horizontal substrate in water has been investigated for both steady and periodic input powers. For steady power conditions, the heat flux was varied ...
A computational and experimental study of flush heat sources in liquids
(Monterey, California. Naval Postgraduate School, 1990-06)
A numerical investigation of two-dimensional natural convection flow and heat transfer from a substrate-mounted flush heat source immersed in a liquid-filled square enclosure was conducted. The study is relevant to direct ...
Heat transfer studies on a rectangular channel with offset plate fins
(Monterey, California. Naval Postgraduate School, 1993-12)
Convective heat transfer characteristics of a liquid cooled rectangular channel, containing offset plate fins were investigated experimentally. The selected geometry was a 10x model of the fluid circulation passages in the ...
Natural convection above a horizontal heat source
(Monterey, California. Naval Postgraduate School, 1993-03)
An investigation of natural convection heat transfer from a flush mounted heater on a larger horizontal substrate in water has been conducted. The focus of the present investigation was on the buoyant flow above the heat ...
Visualization of gas tungsten arc weld pools.
(Monterey, California. Naval Postgraduate School, 1991-09)
Surface flow visualization of Gas Tungsten Arc weld pools
for HY-80 steel is presented using a pulsed laser light source
and a conventional night-vision image-intensif ier tube
equipped video camera. Visualization of ...
A correlation of welding solidification parameters to weld macrostructure
(Monterey, California. Naval Postgraduate School, 1992-06)
A 3-D finite difference model simulating single pass autogenous welds was used to predict the temperature fields in HY-80 steel arc weldments at various powers and torch velocities. From the predicted temperature field, ...
Natural convection cooling of a three-by-three array of leadless chip carrier packages in a dielectric liquid
(Monterey, California. Naval Postgraduate School, 1994-03)
Liquid cooling of a three-by-three array of commercially available leadless chip carrier packages, mounted on a ceramic substrate was examined. Baseline data were obtained for cooling with pure dielectric liquids. The ...
Effects of power pulsations on natural convection from discrete heat sources.
(Monterey, California: U.S. Naval Postgraduate School, 1991-03)
The natural convection heat transfer from an array of heaters flush mounted on a vertical test surface in response to both
step and periodic input power has been investigated. Baseline surface temperature measurements in ...
Weldpool flow visualization studies during gas tungsten arc welding of steel and aluminum.
(Monterey, California. Naval Postgraduate School, 1992-03)
A flow visualization study of current distribution effects on
weld pool stirring in GTA steel welds is presented using a pulsed
ultraviolet laser vision system. Weld pool stirring is almost
eliminated in HY-80 steel by ...
Convective heat transfer from discrete heat sources in a liquid filled vertical channel.
(Monterey, California. Naval Postgraduate School, 1992-12)
Natural, mixed and forced convection liquid cooling of
discrete heat sources in a vertical channel were investigated
experimentally. Ten heat sources were flush mounted to one
wall of a water filled channel, while the ...
