Solidification Shrinkage

This paper aims to study the effects of rare earth Cerium addition on mobility, solidification shrinkage, casting microstructure and hot tearing tendency of Al-4.5Cu alloy. Results show that by adding appropriate rare earth Cerium into the Al-4.5Cu alloy, the viscosity of liquid metals can be reduced, the mobility of alloy can be increased, and the shrinkage during the solidification of liquid metal can be reduced. Further more, as the tendency of alloy dendrite is inhibited and the microstructure of the casting alloy is improved, the alloy can be purified, its thermal conductivity can be enhanced, and the hot tearing tendency of it can be decreased remarkably. It proves that when rare earth Ceriumaddition in Al-4.5Cu alloy is 4w%, the mobility of Al-4.5Cu alloy will be the maximum, and its volume shrinkage will be the least. Meanwhile, the grains of alloy are refined and round. The alloy also shows the lowest hot tearing tendency.

The present work investigates the energy equation of a general fluid, Newtonian or non-Newtonian, with variable thermal conductivity in turbulent flow. The usual energy equation, without the dissipation terms, is taken into account with the fluctuating terms in the temperature as well as in the thermal conductivity. The energy equation is written for the average temperature, for the fluctuating temperature one as well as for the square of the fluctuating temperature. Besides the usual Reynolds stresses, a new term appears, which is the product of the fluctuation of the thermal conductivity and the gradient of the temperature fluctuation. This new term is interpreted and introduced in the energy equation where the variable is the square of the temperature fluctuation where new terms appear. A possible physical interpretation is given to the different terms. Assuming a polynomial relation between thermal conductivity and temperature it is then possible to write an expression for the average and the fluctuating thermal conductivity. The expressions are then simplified on the basis of physical and mathematical considerations. Specifically, the heat flux due to the fluctuating thermal conductivity is then expressed as the product of the derivative of the thermal conductivity with the mean temperature to the gradient of the square of the temperature fluctuation. Further considerations allow to write a new energy equation of the average temperature which include the new term. The solution of this energy equation is possible with the coupled solution of the equation for the square of the fluctuating temperature. The introduction of this new term in the energy equation can be of some importance in problems related to liquid metals flowing in turbulent flow and/or in very low temperature applications where the thermal conductivity becomes very high.
