Heat transfer coefficients for slab shaped products subjected to heating

open access: yesInternational Communications in Heat and Mass Transfer, 1994
Abstract An analytical model was obtained to determine heat transfer coefficients for slab shaped food products heated in a convection oven. The variation of the center temperature of the products was measured and converted into dimensionless form.
