Porous heat exchangers-classification, construction, application

Determining the specific surface area of ceramic foams: The tetrakaidecahedra model revisited

“…high porosity, large external surface area and high mechanical strength) ceramic foams are excellent candidates for a variety of industrial applications. The first commercial application of ceramic foams reported in the literature was their use as filters for molten metals (Maiorove et al, 1984;Brockmeyer and Aubrey, 1987). In the past two decades, ceramic foams have been extensively investigated for a number of other applications including gas filters, heat exchangers, porous burners and catalyst supports.…”

Experimental investigation of the heat exchange intensity

“…is the average temperature coefficient. The heat transfer coefficient is determined according to the equation (2):…”

“…Nowadays, the task of energy saving in various industries, equipment and public utilities is very urgent. For this purpose one use new technologies, new designs, new materials, which include porous metals [1,2]. The use of porous metals is very promising for creation of compact, highly efficient heat exchangers for various purposes, which are the key element of refrigerating units, heat pumps, steam turbine condensers [3,4].…”

Selection of porous materials in marine system design: The case of heat exchanger aboard ships

“…Titanium's natural qualities of strength, low density, ductility and heat transference are often alloyed with various metals to create a hybrid of properties. Titanium steel is lighter and far more resistant to corrosion than regular steels [46]. PMA 2 -Porous Brazed Plate: Brazed porous plate heat exchangers require less floor space due to the high thermal efficiency of the plates as compared to other types of heat exchangers.…”
