Planewall_Q_ND

 

 

The function planewall_Q_ND(Fo, Bi) returns the non-dimensional heat transfer to a bounded plane wall with one edge exposed to convection (x=L) and the other adiabatic (x=0). The supplied values, Fo, Bi represent the Fourier number and Biot number respectively.  The non-dimensional heat transfer is the ratio of the actual to the maximum heat transfer into the wall.  A separation of variables technique is used to solve for the temperature, as explained in section 3.5.2 of Nellis and Klein.

Example:

$UnitSystem SI K Pa J

Fo=0.6

Bi=1.5

Q_hat=planewall_Q_ND(Fo, Bi)

Q_max=1000 [W/m^2]

Q=Q_max*Q_hat

 

{Solution: 

Q=457.4 [W/m^2]

Q_hat=0.4574}
