“…Singh et al [192] reported that the thermal performance of a square channel with aluminum metal foam can be increased by 6 -10% using an array (5 x 5) of impingement jets. Godi et al [193] investigated the heat transfer performance of three-dimensional wall jets coming from a series of circular nozzle outlets over a flat surface. They reported that for a specific diameter, a reduced number of jets provided better [190] performance compared to closely situated jets when the mass flow rate was fixed.…”

Recently, the thermal management of power electronic converters has gained significant attention due to the continuous trend of developing very compact power electronic converters with high power density. With the evolution of power semiconductor devices, high operating temperatures and large thermal cycles have become possible, necessitating a significant improvement in thermal system designs. Researchers have made significant efforts to develop effective thermal management systems for improving the reliability and lifetime of power electronic converters. This article intends to present a thorough review of thermal management systems employed in power electronics cooling. The applied thermal management techniques have been reviewed from the perspective of electrical parameter regulation and heat dissipation control. Regulation of electrical parameters involves active thermal control, which is a method for controlling junction temperature and thermal cycling of power semiconductor devices. The active thermal control implementation processes reviewed in this article consist of increasing overload capacity, manipulating switching and conduction losses, employing modified modulation process, balancing thermal stress at the converter level, and controlling thermal stress at the system level. Control of heat dissipation can be achieved through direct and indirect cooling of power electronic converters with air or liquid as the coolant. The effectiveness and implementation methods of these cooling techniques, such as channel cooling, phase change material-based cooling, immersion cooling, jet impingement and spray cooling, are reviewed in this paper. Moreover, performance-enhancing ideas and challenges for these techniques are discussed. The primary objective of this review paper is to bridge the existing gap in the literature by offering a comprehensive comparison of commonly employed thermal management techniques.

“…Thus, determining the thermophysical properties and rheological behavior of nanofluid to make them applicable in the industry becomes very important. The lubricating power of nanofluids in addition to their unique thermal properties [ [15] , [16] , [17] , [18] , [19] , [20] ] are the reason for using them in different industries such as thermal transformers, military, and electronic [ [21] , [22] , [23] , [24] ]. One substantial parameter affecting nanofluids thermo-physical properties is their viscosity.…”

“…Dakos et al [23] measured temperature and heat fluxes for plane and curved wall jets and AbdulNour et al [24] experimentally investigated the convective heat transfer coefficients on the developing region up to x/b = 20. Godi et al [25,26] reported the results of an experimental study to determine the heat transfer coefficient and to select RANS turbulence model for three-dimensional (3D) plane jets. They showed that the width of the slot influences the Nusselt number only in the developing region.…”

Numerical Simulation of Heat Removal from a Window Slab Partition of a Radiative Coil Coating Oven

In this work, fluid flow and heat transfer performance of a radiative coil coating oven is numerically investigated. In the coil coating oven concept under consideration, porous radiant burners provide the required energy to evaporate the volatile species (solvents) from the applied coating and to promote curing reactions. To avoid the mixing between burners flue gas (with a non-negligible oxygen content) and evaporated (combustible) solvents in the oven (which could lead to a catastrophic oven failure), a semi-transparent window in between both atmospheres is applied. To ensure the window thermal stability during the oven operation, window cooling by wall jets is considered. Different turbulence models were compared against available wall jet heat transfer correlations to select the most suitable for three-dimensional (3D) numerical simulations. Convective heat transfer correlations purposefully developed were embedded in a one-dimensional (1D) window energy model for fast performance characterization, analysing the most influencing parameters—window radiative properties, thickness, inlet temperature and velocity of wall jets, and cooling strategy. The 1D window thermal performance is compared with literature and 3D results considering the full coil coating oven, providing satisfactory confidence on the developed strategy. The 1D model is used for an optimisation study to find the minimum energy consumption while ensuring the safety requirements (maximum window temperature and thermal gradient) are met.
