WebConvection includes both advection (fluid motion) and diffusion (conduction). The conductive component is measured under the same conditions as the convective but for a hypothetically motionless fluid. It is a dimensionless number, closely related to the fluid's Rayleigh number. [1] : 466 WebFo = αt/L^2. When the _____ at t = 0 and held constant at all times, the differential equation for the transient heat conduction problem in a semi-infinite solid can be expressed as (δ^2T/δx^2) = (1/α)* (δT/δt) surface temperature is changed to Ts. Examples of when analytical solutions to heat transfer fail. 1.
