36 -S 42 2. Metal castings can sometimes develop a gap between the casting and mold as the molten metal hardens. The result can be a substantially altered cooling process. Set up a simple heat-transfer model that would let you look at the effect of the gap on the cooling process. Assume the casting and mold are square in shape, with an air gap of thickness das shown in the figure. The mold sits in some ambient room temperature. State clearly all assumptions and develop a corresponding model of the heat transfer problem. Assuming that the casting is aluminum, the mold is diatomaceous earth and the gap is filled with air, see if you can arrive at and summarize some insight into the effect of the gap and its size on the heat transfer process.
Q. Steam in a heating system flows through tubes whose outer diameter is 5 cm and whose walls are maintained at a temperature of 130 °C. Circular aluminum alloy 2024-T6 fins k = 186 W/m.K of outer diameter 6 cm and constant thickness 1 mm are attached to the tube. The space between the fins is 3 mm, and thus there are 250 fins per length of the tube. Heat is transferred to the surrounding air at 25 °C, with a heat transfer coefficient of 40W/m².K. Determine: 1. The increase in heat transfer from the tube per meter of its length as result of adding fins. 2. The efficiency of the fins. 3. Temperature at mid-point of the fins. Note: Equations and any other data required can be taken from textbook/handbook. 130°C 25°C
