WebSolve conduction-dominant heat transfer problems with convection and radiation occurring at boundaries Address challenges with thermal management by analyzing the temperature distributions of components based on material properties, external heat sources, and internal heat generation for steady-state and transient problems.
WebIf your object is a cylinder placed horizontally the characteristic length is determined by the diameter D of the cylinder. The characteristic length is commonly defined as the volume of the body divided by the surface area of the body, i.e. The surface area should include the top and bottom of the cylinder.
