Abstract:

Random process theory has been used to develop statistical relations for the temperature response in an infinitely thick slab when subjected to randomly varying surface temperatures. A realistic seasonaldiurnal temperature cycle with superimposed random hourly variations is used to represent the surface boundary condition. Frequency response, power spectral density, and standard deviation functions are determined as a function of slab depth for various times. For solid propellant material, the temperature drop is very rapid for the diurnal component but is only slightly attenauted for the seasonal cycle. Author
