“…Literature review shows that in recent years much emphasis has been laid on increasing the mechanical properties such as porosity [13], good strength, effect of cell size [2] and energy absorption capacity [2,3] by using different parameters such as foaming agents [15], different alloys with different melting temperature [12] and so on. Complex processes were carried out to get the optimum results.…”

“…However most of scholars have worked on Al foam [5][6][7][8], because Al is cheaper, light weight and easily available. They have found out the different processes [9,10] and mechanical properties for instance porosity %, yield strength, energy absorption capacity [11] by varying the different parameters such as the effect of working temperature [12], addition of ceramic microspheres [8], without foaming agent [13], other foaming agent instead of TiH2 [5], effect of blowing agent composition [14] and so on.…”

Abstract-Metallic foam is a type of cellular solid structure that consists of gas filled in its pores. The cell wall of pores can be opened or closed. Much development has been done in recent years to increase the applications of metallic foam in real life such as clinical, medical and engineering applications. There are various engineering applications such as aerospace, railway industries, heat exchangers, automobile industries and many more. However main emphasis is laid on automobiles. For which it is found that CaCO 3 is the best suitable agent for the manufacture of Mg-foam. However, no research had been done on Dolomite for the fabrication of Mg-foam. In this paper, an attempt is made to use the Dolomite as the foaming agent.

Open-cell Al foams were produced by the replication casting technique in three different pore sizes. All produced foams were physically characterized, determining their relative density, porosity, and pores per inch, as well as their mean pore surface area and diameter. Permeability tests were carried out by means of the injection of a highly pressurized gasoline additive at room temperature and 200 °C, at pressures of up to 25,000 psi. The structural capacity of the studied specimens to conduct fluids at these critical experimental conditions was assessed by means of compression tests in order to determine their mechanical properties after the permeability tests, e.g., energy absorption capacity, Young’s modulus, and plateau stress. It was found that the produced open-cell Al foams were able of conducting the gasoline additive at critical flow conditions of pressure and temperature, without suffering important physical nor structural damage.

“…Metal foams are a new type of material with a wide range of applications because of their excellent properties including light weight, impact energy absorption capacity, specific thermal acoustic properties and low thermal conductivity [16][17][18]. Open porous metallic foams have been used in heat and mass transfer applications, for instance in heat pipes, vapour chambers, and loop heat pipe elements.…”

Abstract. This paper focuses on identification of the impact of porous heated surface on flow boiling heat transfer in a rectangular minichannel. The heated element for Fluorinert FC-72 was a thin plate made of Haynes-230. Infrared thermography was used to determine changes in the temperature on its outer smooth side. The porous surface in contact with the fluid in the minichannel was produced in two processes: sintering or soldering of Fe powder to the plate. The results were presented as relationships between the heat transfer coefficient and the distance from the minichannel inlet and as boiling curves. Results obtained for using a smooth heated plate at the saturated boiling region were also presented to compare. In the subcooled boiling region, at a higher heat flux, the heat transfer coefficient was slightly higher for the surface prepared via soldering. In the saturated boiling region, the local heat transfer coefficients obtained for the smooth plate surface were slightly higher than those achieved from the sintered plate surface. The porous structures formed have low thermal conductivity. This may induce noticeable thermal resistance at the diffusion bridges of the sintered structures, in particular within the saturated boiling region.
