4. Functions Functions return the dimensionless temperature,  * Tslab(xstar, Fo, Bi) Tcyl(rstar, Fo, Bi) Tsph(rstar, Fo, Bi) Function Wizard – User Defined

5. Inputs Dimensionless length, rstar or xstar –rstar = r / R –xstar = x / L Fourier Number - Fo =  t / L 2 Biot Number - Bi = hL / k r R L x L x L = R

6. Semi-Infinite Solid TsemiInf(BCtype, x, alpha, t, k, BC) BCtype - Boundary condition type –1 - Constant Surface Temperature, returns –2 - Constant Surface Heat Flux, returns –3 - Surface Convection, returns x - distance from surface alpha -  = k /  c [m 2 /s] t - time k - conduction coefficient [W/m-K] –Only necessary for BCtype 2 & 3 BC - Boundary condition value –Only necessary for BCtype 2 & 3 –BCtype 2 - BC = q" 0, surface heat flux [W/m 2 ] –BCtype 3 - BC = h, convection coefficient [W/m 2 -K] x
