Thermal performance and pressure drop in a ceramic heat exchanger evaluated using CFD simulations

Heat transfer and pressure drop correlations for finned plate ceramic heat exchangers

“…As demonstrated by Ref. [12] a simulation including three rows of fins is sufficient to obtain practically identical Colburn and friction factor curves, if compared to the simulation conducted with six rows. This simplification reduces the computational costs, as the number of volumes in the mesh decreases drastically.…”

“…A CFD study that used this approach, for one HTHE that could be constructed using finned plates, is presented in Ref. [12].…”

Ceramic high temperature plate‐fin heat exchanger: A novel methodology for thermomechanical design investigation

“…An experimental investigation on thermal performance and pressure drop performance of a sintered silicon carbide OSF heat exchanger prototype was performed by Haunstetter et al 9 He conducted tests at temperatures up to 800°C and pressures up to 5 bar and compared the results with correlations from literature. CFD-simulation studies on thermal performance and pressure drop as well as experimental tests of an OSF ceramic plate heat exchanger made from alumina (Al 2 O 3 ) were carried out by de Mello et al [10][11][12] The HTHE was operated at temperatures up to 800°C and ambient pressure conditions. However, structural failure was observed resulting from thermal-induced stresses at high temperatures.…”

“…[1][2][3] Different studies on ceramic heat exchanger technology are available from literature. CFD-simulation studies on thermal performance and pressure drop as well as experimental tests of an OSF ceramic plate heat exchanger made from alumina (Al 2 O 3 ) were carried out by de Mello et al [10][11][12] The HTHE was operated at temperatures up to 800°C and ambient pressure conditions. Their advantages are high exchanger surface to volume ratio, compact structure, and high efficiency compared with other ceramic heat exchanger types like heat-pipes.…”

Multi-scale thermal analysis approach for the typical heat exchanger in automotive cooling systems

“…Under the current conditions, it is unlikely to cover the full heat exchanger scale by a detailed model. Then many researchers limit their analysis to a representative portion of the exchangers, obtain its own numerical heat transfer and friction correlations [1][2][3][4]. CFD tools are nowadays predicting with a high level of accuracy, yet the performance of a whole heat exchanger is hard to be accurate predicted only by the studying of one portion.…”
