What is Thermal Conductivity? An Overview - Thermtest

Thermal conductivity (often denoted by k,,or ) refers to the intrinsic ability of a material to transfer or conduct heat.It is one of the three methods of heat transfer,the other two being convection and radiation.Heat transfer processes can be quantified in terms of appropriate rate equations.What is Overall Heat Transfer Coefficient - U-factor Most materials are very nearly homogeneous,therefore we can usually write k = k (T).Similar definitions are associated with thermal conductivities in the y- and z-directions (k y,k z),but for an isotropic material the thermal conductivity is independent of the direction of transfer,k x = k y = k z = k..From the foregoing equation,it follows that the conduction heat flux increases with What is Heat Exchanger - Heat Transfer Coefficient - U The overall heat transfer coefficient,U,is related to the total thermal resistance and depends on the geometry of the problem.For example,heat transfer in a steam generator involves convection from the bulk of the reactor coolant to the steam generator inner tube surface,conduction through the tube wall,and convection (boiling) from the outer tube surface to the secondary side fluid.
