This article serves as a possible basis for the introductory lecture to a first course in heat transfer. By making use of a solar still as a practical example many of the important heat transfer concepts may be interestingly introduced. Conduction, convection and radiation and combinations thereof are all important in the analysis of the performance of a solar still. The conservation of energy and mass is applied to the components of the solar still treated as control volumes. The resulting system of simultaneous differential equations simulating the behaviour of the still are then solved numerically. The results thus obtained are compared to experimental observations. Fairly good agreement between the theoretical and experimental results were obtained, for instance the theoretical daily production of fresh water of 3.15 kg/m2 was 5% less than the experimentally measured value, and the maximum temperature of the water in the still was predicted at 15% more than the experimentally measured value of 62°C.

AbstractAlaska pollock (AP) surimi paste was prepared (0–3% salt and 76–84% moisture). The density, specific heat, and thermal conductivity were measured and modelled in temperatures between 25 and 90 °C (R2 > 0.92). The thermal diffusivity (α) function showed a strong dependence on the moisture content and a unique salt dependence at 84% of the moisture content and applied to the heat transfer simulation of surimi paste. The simulation model coupled with the empirical thermal properties accurately predicted the heat penetration curves during heating with RMSE values ranging from 0.43 to 1.22 °C. The salt dependence on thermal diffusivity was identified and modeled only at 84% moisture content. With a model for 84% moisture content, the RMSE value of 3% salt content decreased from 1.11 °C to 0.56 °C. This study demonstrated that an accurate prediction of the heat transfer of the surimi paste needs to be coupled with the nonlinear thermal diffusivity functions.

Airflow and heat transfer simulation was conducted for a double-skin façade (DSF) system equipped with shading devices in the cavity, using computational fluid dynamics (CFD) with RNG turbulence model and PISO algorithm, for five conditions of slat angles (θ=0°, 30°, 45°, 60°, 90°). The present study indicates that the presence of shading devices influences the temperatures, the ventilation rate and the air distribution in the DSF system. Besides, the different angles will make different influences.
