A hybrid computational method via CFD (computational fluid dynamics) and artificial intelligence was developed for studying heat transfer in nanofluid. The finite volume approach used to solve the flow equations through a pipe containing CuO nanofluid obtained temperature distribution develop intelligence-based models. Optimization of tree-based ensemble models predicting values based on input features x-coordinate y-coordinate were carried out. ensembles, i.e., Random Forest, Gradient Boosting, Extra Tree, Adaboost Decision Trees, are optimized using Fuzzy-based Bee Algorithm (FBA) enhance their performance. Tree model achieved an excellent fitting with R2 criterion 0.99779, RMSE 1.7977E-01. Forest slightly higher correlative accuracy, 0.99865, value 1.4336E-01. Trees also demonstrated strong performance, 0.99846, 1.5394E-01. However, Boosting exhibited lower score 0.99258, 3.4090E-01.

Abstract Heat exchangers are crucial in transferring heat and finding applications across various industries. Numerous strategies have been devised to improve optimize the transfer process within these systems. Among these, passive methods garnered significant attention for their ability operate without external power consumption. This article examines recent experimental computational studies conducted by researchers since 2018 on enhancement techniques, especially twisted tape, wire coil, swirl flow generator, others, boost thermal efficiency of aid designers adopting augmentation compact exchangers. Recently, researchers' new class maldistribution devices, referred as has gained attention; which enhances convective introducing into main disrupting boundary layer at tube surface through alterations geometry. Twisted tape inserts devices that demonstrate better performance laminar compared turbulent flow. Conversely, other techniques like ribs, conical nozzles, rings generally more effective than A research trend is utilization nanofluids combination with turbulators, exchangers, can reduce exergy losses overall coefficient effectiveness exchanger.

The limited operational range of electric vehicles (EVs) continues to be a significant hurdle their advancement. Insulated Gate Bipolar Transistor (IGBT) embedded in the inverters these generates amounts heat while operating and greatly impacts vehicle's overall performance. To improve efficiency EVs, present study puts forward new thermal management system comprising multi-layer microjet sink with supercritical carbon dioxide (sCO2) as working fluid for cooling IGBTs high fluxes. diode pairs are modeled based on motor inverter Toyota Prius. Each IGBT its pair is direct bound copper beneath baseplate sink, generating fluxes between 120–360 W/cm2. Inlet temperatures ranging from 25 35 °C mass 500–2000 kg/m2 s were used this study. numerical simulations performed using finite volume method, procedure validated against experimental data. Results show that maximum global transfer coefficient sCO2 60.4 kW/m2 higher inlet temperature can positively or negatively affect thermohydraulic behavior depending conditions. Increasing at q" < 360 W/cm2 enhances over different layers up 33 %, ≥ W/cm2, convective reduced temperature. Despite lower water fluxes, exhibits 5 times better uniformity, showing promising potential an advanced coolant future cutting-edge systems.
