A study of combined heat and mass transfer by free convection from a controlled environment to a plate at -310°F
(1967)
An experimental study of heat and mass transfer in free convection from a controlled environment to a plate at liquid nitrogen temperature (-310°F) has been made. The temperature of the environment was varied from 36°F to ...
Unsteady-state performance of water-drive gas reservoirs
(1967)
Although it has long been realized that gas recovery from a water-drive gas reservoir may be poor because of high residual gas saturation left in the water-invaded portion of the reservoir, it appears that only limited ...
