WebThe surface area (A) for transferring heat through the pipe (neglecting the pipe ends) is directly proportional to the radius (r) of the pipe and the length (L) of the pipe. A = 2 π r … WebCylindrical fin type of turbulators has been placed circumferentially separated by 90° on the outer side of an inner pipe at a regular pitch. Experimental studies were undertaken for different air flow rates in a turbulent regime whose Reynolds number range between 2500 and 10000. ...

WebDetails. The axial temperature distributions for a fin of uniform cross section for an adiabatic tip and a tip with convection are:. for a rectangular fin:,, for a pin fin:,, where and are the base and ambient air temperatures, is fin length (m), is position down the fin (m), is the convection heat transfer coefficient, is the thermal conductivity of the material (W/(m … Webcylinder. From the data, heat transfer coefficients of each fin can be estimated. Apparatus. The apparatus consists of four different fin configurations. The heater and base of the fin are surrounded by insulation to prevent any heat loss. Mounted along the length of the fin are five to seven thermocouples.
