Definition | A <FOURIER NUMBER> is a <Property> that is a dimensionless group which arises naturally from the nondimensionalization of the conduction equation. It is very widely used in the description and prediction of the temperature response of materials undergoing transient conductive heating or cooling. It is given by Fo = lambda.t/(c_p.rho.l^2) = a.t/l^2 where lambda is<THERMAL CONDUCTIVITY>, t is time, c_p is<SPECIFIC HEAT CAPACITY AT CONSTANT PRESSURE>, rho is <MASS DENSITY>, l is <LENGTH> and a is <THERMAL DIFFUSIVITY> |
