HTE SIMILARITY OF NON-STATIONARY HEAT TRANSFER OF SOLIDS UNDER IDENTICAL CONDITIONS,
Abstract
An analysis was made of the investigative results of unsteady heat exchange in solid bodies under identical conditions of practical importance. These investigations allow us to formulate a fourth requirement of identity of temperature fields in bodies heated (cooled) in identical conditions, and they further allow us to formulate a possibility of transfer from boundary conditions of a model to the boundary conditions of nature in any case where the identity of temperature fields takes place, and, in more common cases, where the identity of fields is not present. As objects for investigation, measuring bodies q of the calorimeters were used. A measuring body represents a cylinder with one heat exchange surface (base at x = R), the remaining body surface being heat-insulated in such a way that it allows the measuring body to be regarded as a cylindrical cutout from half of an infinite plate (0 < x > R). Experimental results were processed according to the method of average temperatures and according to the method of consecutive intervals.
