ملخص

Thermal diffusivities of Indian major carp Catla (Catla catla) and Rohu (Labeo rohita) fish were determined by using a one-dimensional (1D) Fourier equation applied to a cylinder. Experiments were conducted by cooling the different quantities of individual fish with ice in an insulated box. Time-temperature records were used to determine the thermal diffusivity. The values of thermal diffusivities of fish cooling with ice were ranged from 6·6012 to 3·2475×10-8 m-2 s-1 and 6·6481 to 5·4267×10-8 m-2 s-1 for Catla and Rohu fish, respectively. It was observed that the thermal diffusivity decreases with an increase in the weight of the fish. A logarithmic model adequately described the relationship between thermal diffusivity α and mass of fish m, with values for the coefficient of determination of 0·9949 and 0·9996, and standard errors of 0·088 and 0·0006 for Catla and Rohu fish, respectively.
