“…The same setup was used for pressure drop measurements. They reported similar findings as Kim et al [42] with regards to the impact of the porosity and ppi values, but further analyzed the foam properties using the inertia and form coefficient [61], and permeability. They compared their results with available correlations for the pressure drop and found no model was able to provide satisfactory agreement.…”

Abstract:Recent advances in manufacturing methods open the possibility for broader use of metal foams and metal matrix composites (MMCs) for heat exchangers, and these materials can have tailored material properties. Metal foams in particular combine a number of interesting properties from a heat exchanger's point of view. In this paper, the material properties of metal foams and MMCs are surveyed, and the current state of the art is reviewed for heat exchanger applications. Four different applications are considered: liquid-liquid, liquid-gas and gas-gas heat exchangers and heat sinks. Manufacturing and implementation issues are identified and discussed, and it is concluded that these materials hold promise both for heat exchangers and heat sinks, but that some key issues still need to be solved before broad scale

“…As expected, the pressure-drop increases with increasing airflow velocity in similar trends to those reported in [2,4,6,7,[10][11][12][13][14], but a third order (rather than second order) polynomial provides a better fit to the data over the entire velocity range. The different regimes can be identified by using a graphical separation method used by Boomsma et al [11] and adopted in many related works [4,6,9,13,15,16]. Figure 5 shows the various regimes and transitional regions including the commonly-studied Forchheimer regime, which was found to lie between 4 and 12 m sˉ¹.…”

“…The pressure-drop across monolithic (bulk) porous metals has been widely investigated, including studies reported in [1][2][3][4][5][6]. In many engineering systems, for low (laminar) flow velocities, the relationship between pressure-drop and airflow velocity is ably described by the Hazen-Darcy or Forchheimer equation [3,7,8].…”

“…When unidirectional airflow passes through those loose media, air compressibility is negligible due to slight pressure drops, and velocity in the flow direction is generally considered constant [21][22][23]. However, in contemporary air-bearing feeding systems, porous media fabricated by sintered metal that have a small porosity also receive great attention.…”

Sintered metal porous media currently plays an important role in air bearing systems. When flowing through porous media, the flow properties are generally represented by incompressible Darcy-Forchheimer regime or Ergun regime. In this study, a modified Ergun equation, which includes air compressibility effects, is developed to describe friction characteristic. Experimental and theoretical investigations on friction characteristic are conducted with a series of metal-sintered porous media. Re = 10 is selected as the boundary for a viscous drag region and a form drag region. Experimental data are first used to determine the coefficient α in the viscous drag region, and then the coefficient β in the form drag region, rather than both simultaneously. Also, the theoretical mass flow rate in terms of the modified Ergun equation provides close approximations to the experimental data. Finally, it is also known that both the air compressibility and inertial effects can obviously enhance the pressure drop.
