“…Because numerical analysis allows for a more realistic image of the heat flow behaviour of fluids within the MCHS, most studies currently employ numerical approaches (Gök, 2017;Gök, Selçuk and Gök, 2021;Gok, 2022) (Pirhan, Gök and Gök, 2020). Thus, the primary goal of this study is to perform a computational analysis on the thermo-fluidic behaviour of a ZrB2 composite MCHS reinforced with SiC and CNT to assess its suitability for use in electronic components.…”

As a result of the development of micro-electro-mechanical systems (MEMS), it is now feasible to achieve enormous heat transfer, even though electrical and electronic devices have more compact spaces. A heat sink is a device that collects significant amounts of heat from various electrical and electronic surfaces and then releases that heat into the surrounding environment. In the current study, a ceramic microchannel heat sink (MCHS) with a rectangular channel having a length of 10 mm and dimensions of 57×180 μm was investigated numerically. Because ceramics are valuable materials that can withstand corrosive environments and extreme temperatures, they are statistically analyzed to evaluate whether a substance can work under such harsh conditions. Firstly, the finite element approach was used to solve the governing equations of the solid domain as ZrB2 composites and the fluid domain as water. Subsequently, a numerical analysis was conducted on an MCHS constructed from ZrB2 composites reinforced with SiC and CNT in a variable proportion of 20 vol.% and 10 vol.%, respectively. The results reveal the most significant temperature reduction for an ultra-high heat flux for the ZrB2 composite reinforced with 20 vol.% SiC, followed by the ZrB2 composite reinforced with 20 vol.% SiC & 10 vol.% CNT at Reynolds number 250. The fundamental causes of the exceptional heat transfer rate are the high surface density of the microchannel and the excellent thermal conductivity of the UHTCs.

“…17 So far, researchers have conducted extensive research on the modeling of cutting force of difficult-to-machine materials. 18,19 In order to explore the impact of particles on cutting force, Pramanik et al 20 proposed a cutting force predicted model for SiC/Al 2 O 3 composites. The model divided the cutting force into three aspects: chip formation force, ploughing force, and particle fracture force.…”

The machining process of SiCp/Al composites is considerably difficult because of the addition of ceramic particles. As an effective machining method, ultrasonic vibration-assisted turning is used to process SiCp/Al composites, which can effectively reduce the cutting force, improve the surface quality, and reduce the tool wear. This study developed a cutting force prediction model for ultrasonic vibration-assisted turning of SiCp/Al composites, which comprehensively considers the instantaneous depth of cut and the instantaneous shear angle. This model divides the cutting force into the chip formation force considering the instantaneous depth of cut, the friction force considering the influence of SiC particles at tool-chip interface, the particle fracture force, and the ultrasonic impact force in the cutting depth direction. By comparing the predicted value of the main cutting force with the experimental values, the results present the same trend, which verifies the feasibility of the cutting force prediction model. In addition, the influence of vibration amplitude, depth of cut, and cutting speed on the main cutting force is analyzed. The systematic cutting experiments show that ultrasonic vibration-assisted turning can significantly reduce the cutting force and improve the machinability of SiCp/Al composites.

Rigorous emission regulations call for more efficient passive control catalysts for exhaust gas aftertreatment without affecting the internal combustion process and CO2 emissions. Although the state-of-art ceramic honeycomb substrate designs provide high surface area and a degree of flexibility for heat and mass transfer adaptations, additional emission reduction benefits can be achieved when more flexible designs to provide effective thermal management are introduced. The conventional cordierite honeycomb substrates are manufactured by extrusion; therefore, only substrates with straight channels can be fabricated. This study aims to highlight any design limitations of conventional substrates by employing additive manufacturing as the main method of manufacturing diamond lattice structures using DLP (digital light processing) technology. Both conventional substrates and diamond lattice structures are studied numerically and experimentally for flow through resistance and temperature distribution. Numerical predictions and experimental results showed good agreement. The results show the increase of the axial temperature distribution for diamond lattice structures and a significant decrease of the pressure drop (38–45%) in comparison with the benchmark honeycomb with similar surface area.
