thermal conductance
thermal conductancen.1. A measure of the ability of an object to allow the flow of heat from its warmer surface through the object to its colder surface, determined as the heat energy transferred per unit of time divided by the temperature difference between the two surfaces, expressed in watts per kelvin. The conductance of an object equals the conductivity of its material times its surface area (cross-section) divided by the distance between the two surfaces (thickness).2. The reciprocal of thermal resistance, usually measured in units of watts per kelvin.thermal conductance
thermal conductance[′thər·məl kən′dək·təns] (thermodynamics) The amount of heat transmitted by a material divided by the difference in temperature of the surfaces of the material. Also known as conductance. thermal conductanceThe time rate of flow of heat through a unit area of material from one of the faces of the material to the other, for a unit temperature difference between the two faces, under steady-state conditions.MedicalSeeconductance |
