CONDUCTION HEAT TRANSFER Heat TransferCONDUCTION HEAT TRANSFERConduction heat transfer is the transfer of thermal energy by interactions betweenadjacent atoms and molecules of a solid.EO 1.6 Given Fourier’s Law of Conduction, CALCULATE theconduction heat flux in a rectangular coordinate system.EO 1.7 Given the formula and the necessary values,CALCULATE the equivalent thermal resistance.EO 1.8 Given Fourier’s Law of Conduction, CALCULATE theconduction heat flux in a cylindrical coordinate system.ConductionConduction involves the transfer of heat by the interaction between adjacent molecules of amaterial. Heat transfer by conduction is dependent upon the driving "force" of temperaturedifference and the resistance to heat transfer. The resistance to heat transfer is dependent uponthe nature and dimensions of the heat transfer medium. All heat transfer problems involve thetemperature difference, the geometry, and the physical properties of the object being studied.In conduction heat transfer problems, the object being studied is usually a solid. Convectionproblems involve a fluid medium. Radiation heat transfer problems involve either solid or fluidsurfaces, separated by a gas, vapor, or vacuum. There are several ways to correlate the geometry,physical properties, and temperature difference of an object with the rate of heat transfer throughthe object. In conduction heat transfer, the most common means of correlation is throughFourier’s Law of Conduction. The law, in its equation form, is used most often in its rectangularor cylindrical form (pipes and cylinders), both of which are presented below.Rectangular (2-4)Qk ADTDxCylindrical (2-5)Qk A^{}DTDrHT-02 Page 6 Rev. 0
