Effect of melt superheat on heat transfer coefficient for aluminium solidifying against copper chill, J. Mater. Sci. 26, 1729-1733.N.A. El-Mahallawy, A.M. Assar, Effect of melt superheat on heat transfer coefficient for the aluminium solidifying against copper chill, J. Mater. Sci. 26 (...
The interfacial heat transfer coefficient (IHTC) is an important thermophysical parameter in hot stamping processes and must be identified not only to retain the full mechanical strength of formed components, but also to optimise the production rate. In this work, a novel experimental facility was ...
interfacial heat transfer coefficientaluminium castingIn this study, the interfacial heat transfer coefficient between the casting and the mould, h, for the evaporative pattern casting (EPC) of A356 aluminium alloy is measured. The data obtained, which present h as functions of time and/or casting...
This paper investigates the semicircular fin efficiency considering the fact that both thermal conductivity of the fin material and the heat transfer coefficient for dissipation of heat from the fin surface are temperature dependent and can render changes in fin efficiency for large temperature ...
As an important role in the calculation of the effective heat transfer coefficient, the metal temperature at the mold/metal interface is calculated using an extrapolation technique and an inverse scheme. A lump capacity method is also utilized to estimate the average values of the effective heat ...
Copper, aluminium, and nickel billets were heated and then subjected to cooling by water spray systems and immersion in water and mixtures of water and organic agents. The temperature close to the surface was measured and used for the calculation of the heat transfer coefficient by the implicit ...

Thus, in order to increase the rate of heat dissipation from heatsinks, it is necessary to increase either their thermal conductivity, heat transfer coefficient, or surface area [82]. Concerning wearable TEGs, the heatsinks are cooled either by phase change cooling (active cooling) or natural...
The heat transfer coefficient of a coiled tube heat exchanger is higher than that of a straight tube heat exchanger. These heat exchangers are also eligible for thermal expansion and clean fluids due to impossibility of cleaning process [22]. Aluminium alloys for cryogenics and stainless steels ...
The volume fraction of Alumina/Aluminium oxide and Cuprum/Copper are boosting the thermal phenomena. However, compared [Math Processing Error]ϕ1, the thermal profiles in the case of [Math Processing Error]ϕ2 are more obvious. Due to the nanoparticle volume fractions, the behaviour of these...
