Thermal gradient in copper

  1. Jan 11, 2012 #1

    Suppose a copper block is heated on one side so that one end is at 800K. Given the dimensions of the copper block, is there a way of calculating the temperature of a point in the block distance x from the heated end after a given time?

    With many thanks,

    This is a standard problem exhaustively treated in, for example, Mikhailov and Ozisik's "Unified analysis and solutions of heat and mass diffusion".

    If it can be assumed that there are no heat losses from the sides of the block then the equation for rate of heat flow is:
    ΔQ/Δt = k A Δθ/Δx Δθ/Δx is the temperature gradient
