“…Madani et al [149] concluded that the flow boiling in metal foam increases the heat transfer coefficient by 2-4 times at low vapor quality, with the copper foam porosity of 0.97 and pore density of 36 PPI. Recently, Kouidri and Madani [150] examined the effects of various metal foam samples, made of copper, NiFeAlCr and inconel with the same porosity of 0.93 and 20 PPI, on flow boiling heat transfer characteristics. Results showed that copper foam improves the heat transfer by a factor of 1.3-3, while the other two samples has a negative influence on the heat transfer.…”

High porosity metal foams offer large surface area per unit volume and have been considered as effective candidates for convection heat transfer enhancement, with applications as heat sinks in electronics cooling. In this paper, the research progress in thermo-hydraulic performance characterization of metal foams and their application as heat sinks for electronics cooling are reviewed. We focus on natural convection, forced convection, flow boiling, and solid/liquid phase change using phase change materials (PCMs). Under these heat transfer conditions, the effects of various parameters influencing the performance of metal foam heat sink are discussed. It is concluded that metal foams demonstrate promising capability for heat transfer augmentation, but some key issues still need to be investigated regarding the fundamental mechanisms of heat transfer to enable the development of more efficient and compact heat sinks.

“…According to Wang et al [8], the increase in heat transfer intensity is due to induced flow disturbances in the boundary layer, more intensive mixing of vapour and liquid and increased effective thermal conductivity. Kouidri and Madani [2] also noted the great importance of thermal conductivity. These authors have shown that when boiling in a channel filled with highly conductive copper foam, heat transport increases by 130 to 300%, with an average increase in pressure drop by 42%.…”

“…Works in this area have been carried out for several years. The authors of [1,2] have shown that the presence of foam on the boiling surface reduces the vapour bubbles nucleation temperature and shifts the boiling crisis towards much higher heat flux densities. Hu et al [3] report that the heat transfer coefficient recorded when during flow of boiling refrigerant through the channels of refrigeration evaporators filled with foam is 1.5 to 4 times higher than for boiling in evaporators without foam.…”

“…Kouiduri and Madani [2] argue that methods used to calculate pressure drop in gasliquid flow in hollow channels should not be applied to flow through metallic foams. The attempt at using the Lockhart-Martinelli method, the Bankoff method and the Friedel method in their original forms described by these researchers shows too large discrepancies in the calculated and measured pressure drop values.…”

This paper describes experimental investigations of single-phase and two-phase gas–liquid flow through channels with a diameter of 20 mm and length of 2690 mm, filled with metal foams. Three types of aluminium foams with pore densities of 20, 30 and 40 PPI and porosities ranging from 29.9% to 94.3% were used. Air, water and oil were pumped through the foams. The tests covered laminar, transitional and turbulent flow. We demonstrated that the Reynolds number, in which the hydraulic dimension should be defined based on foam porosity and pore diameter de = ϕdp/(1 − ϕ), can be used as a flow regime assessment criterion. It has been found that fluid pressure drops when flowing through metal foams significantly depends on the cell size and porosity of the foam, as well as the shape of the foam skeleton. The flow patterns had a significant influence on the pressure drop. Among other things, we observed a smaller pressure drop when plug flow changed to stratified flow. We developed a model to describe pressure drop in flow through metal foams. As per the proposed methodology, pressure drop in single-phase flow should be determined based on the friction factor, taking into account the geometrical parameters of the foams. We propose to calculate pressure drop in gas–liquid flow as the sum of pressure drops in gas and liquid pressure drop corrected by the drop amplification factor.

“…According to the mentioned literature survey, previous investigations have proved that the high-porosity metallic foams are usually not ideal and optimal for heat-exchange systems. The available thermal-hydraulic data demonstrate that the mediocre augmentation in the heat transfer does not justify the considerable increase in the pressure drop, especially in the CHXs (Sertkaya et al , 2012; Huisseune et al , 2015; Kouidri and Madani, 2017; Han et al , 2012).…”

Purpose This study aims to computational numerical simulations to clarify and explore the influences of periodic cellular lattice (PCL) morphological parameters – such as lattice structure topology (simple cubic, body-centered cubic, z-reinforced body-centered cubic [BCCZ], face-centered cubic and z-reinforced face-centered cubic [FCCZ] lattice structures) and porosity value ( ) – on the thermal-hydraulic characteristics of the novel trussed fin-and-elliptical tube heat exchanger (FETHX), which has led to a deeper understanding of the superior heat transfer enhancement ability of the PCL structure. Design/methodology/approach A three-dimensional computational fluid dynamics (CFD) model is proposed in this paper to provide better understanding of the fluid flow and heat transfer behavior of the PCL structures in the trussed FETHXs associated with different structure topologies and high-porosities. The flow governing equations of the trussed FETHX are solved by the CFD software ANSYS CFX® and use the Menter SST turbulence model to accurately predict flow characteristics in the fluid flow region. Findings The thermal-hydraulic performance benchmarks analysis – such as field synergy performance and performance evaluation criteria – conducted during this research successfully identified demonstrates that if the high porosity of all PCL structures decrease to 92%, the best thermal-hydraulic performance is provided. Overall, according to the obtained outcomes, the trussed FETHX with the advantages of using BCCZ lattice structure at 92% porosity presents good thermal-hydraulic performance enhancement among all the investigated PCL structures. Originality/value To the best of the authors’ knowledge, this paper is one of the first in the literature that provides thorough thermal-hydraulic characteristics of a novel trussed FETHX with high-porosity PCL structures.
