Bulk temperature in heat transfer
WebBulk Temperature. Bulk temperatures of the flow tbx were obtained by adding to the initial temperature increments of temperature equivalent to the total amount of heat generated between the starting point of heating and the measurement point. From: Experimental Heat Transfer, Fluid Mechanics and Thermodynamics 1993, 1993. WebThe concept of the bulk temperature is that adiabatic mixing of the fluid from a given cross section of the duct will result in some equilibrium temperature that accurately reflects the...
