Optimal experimental design for the parameter estimation of conduction heated foods

Simultaneous estimation of thermal conductivity and volumetric heat capacity for solid foods using sequential parameter estimation technique

“…Poulsen (1982) and Martínez-Monzó, Barat, González-Martínez, Chiralt, and Fito (2000) measured thermal conductivity based on the solution of one-dimensional transient heat conduction equation for infinite cylinder subjected to constant surface temperature using only the first term of Fourier's series solution utilizing regression analysis. Recently there is great interest in simultaneous estimation of thermal conductivity and heat capacity (Nahor, Scheerlinck, Van Impe, & Nicolaı, 2003;Nahor, Scheerlinck, Verniest, De Baerdemaeker, & Nicolaı, 2001;Zhu et al, 2007). The objectives of this research work were: to develop a computer program for simultaneous estimation of thermal conductivity and volumetric heat capacity from transient temperature measurements using sequential parameter estimation technique, to use Monte Carlo simulation to validate the computer algorithm and to investigate the effect of sensor position, measurement error and heating time on parameter estimation.…”

Optimal dynamic heat generation profiles for simultaneous estimation of thermal food properties using a hotwire probe: Computation, implementation and validation

“…In practice, identifiability of thermophysical parameters requires heat generation input profiles ensuring that the effect of measurement uncertainties are minimized, resulting in robust parameter estimates. In previous research (Nahor et al, 2001(Nahor et al, , 2003 it was shown that in case of traditional heating strategies with constant heat generation profiles and noise corrupted temperature responses an estimation procedure might result in parameter estimates which deviate from the real physical parameter values to a large extent. Aiming at a simultaneous estimation of conduction heat transfer parameters we are left with the question whether the numerical values of the estimates correspond to physically meaningful heat transfer parameters or not.…”

“…Recent interests are directed towards the simultaneous estimation of the thermal conductivity and heat capacity by means of single or dual heat probe methods (Bristow, Bilskie, Kluitenberg, & Horton, 1995;Bristow, Kluitenberg, & Horton, 1994;Muramatsu, Tagawa, Kasai, Sakai, & Fukushima, 1999;Nahor, Scheerlinck, Verniest, De Baerdemaeker, & Nicolaï , 2001;Nahor, Scheerlinck, Van Impe, & Nicolaı¨, 2003;Tagawa, Kitamura, Muramatsu, & Murata, 1996).…”
