Stagnation point heat transfer in a gas undergoing relaxation of its
internal energy is examined by solution of the equations of motion
using the two temperature approach of Wang Chang and Uhlenbeck.
The results are presented in parametric form and show that relaxation effects produce an adiabatic wall temperature above...
Heat transfer measurements have been made from a long (L/D = 15)
horizontal cylinder in water parallel to a heated vertical wall. The
cylinder and wall boundary conditions were isothermal, and they were
maintained at equal temperatures. The investigation covered Rayleigh
numbers based on cylinder diameter from 400,000 to 10,000,000....
Investment casting has been an important form of metal casting
for many years, but little is understood about the fluid flows that
occur during mold filling. A key to quality castings is the
understanding and control of the fluid flows that are present when the
mold is filled with molten...
Centrifugal casting has been a successful
technique for quickly filling molds, but little is
understood about the fluid flow characteristics that occur
during filling. The understanding of these flow
characteristics and the application of this knowledge
should improve the quality of metal parts cast by this
process. The subject of...
An experimental investigation has been performed to determine the
forced convection heat transfer due to three-dimensional air flow over
a flat plate as a function of angle of attack and free stream velocity.
The experimental method employed a transient thermal technique and
placed the convecting surface next to the exhaust...
An experimental study has been made of the local natural convective
heat transfer coefficient around the circumference of a heated
horizontal cylinder oscillating vertically in water. The heat transfer
surface consisted of a 1 3/8-inch diameter cylinder with a small test
section imbedded in its surface. This enabled data to...
