Thermal management is a critical challenge in advanced systems such as electric vehicles (EVs), electronic components, and photoelectric modules. alleviation carried out through the cooling which coolant heat exchangers are key components. The study examines recent literature on nanofluids exchanger tubes along with state-of-the-art concepts being tested for transfer intensification. performance of several common tubes' geometries/configurations effectiveness novel augmentation mechanisms presented. Promising results have been reported, showing improved parameters use intensification like turbulators, fins, grooves, variations temperature flow velocity. These enhance dispersion stability, achieve more uniform distribution, reduce boundary layer thickness, resulting lower tube wall temperatures. Moreover, introducing pulsations magnetic effects further enhances particle mobility exchange. However, there limitations, increased frictional losses pressure drop due to effects. combination nanofluids, geometries, turbulators holds great promise highly efficient future. also presents bibliometric analysis that offers valuable insights into impact visibility research integration systems. aid identifying emerging trends advancing field towards compact systems, paving way future advancements.

Laser powder bed fusion (LPBF) of multi-scaled structures is a prominent direction pursued by innovative designs and engineering applications. However, understanding the impact scale effect on effectiveness actual pressing challenge. This work investigates influence structure surface morphology mechanical property fabricating tensile samples with gauge diameters ranging from 0.2 mm to 5.0 mm. For hatching scanning strategy, roughness drastically reduces ∼51% as diameter increases. appears be coupling results heat accumulation, molten pool at end single-track, overlap between multi-tracks within layer, successive rotational buildup layers. Moreover, decreasing substantially strength. Fortunately, hatching-contour strategy proposed eliminate These efforts provide essential guidance for broader application structures.

Lattice structures based on Triply Periodic Minimal Surfaces (TPMS) have been extensively studied in the field of heat exchange due to advantages they can offer terms increased area and enhanced convective phenomena, thanks their intricate geometry. Numerous studies conducted fluid motion within these structures, confirming that Computational Fluid Dynamics (CFD) simulations accurately replicate thermo-fluid dynamic behavior. However, such are computationally expensive may be difficult integrate larger models whole system. Traditionally, exchanger design relies transfer coefficient correlations non-dimensional groups, especially when dealing with turbulent flow. This study proposes a single correlation, results series CFD simulations, calculate for various fluids different TPMS topologies geometries. is achieved through careful selection characteristic lengths groups considered. Within an acceptance range ±20%, predictive capability correlation proved valid three distinct topologies: Gyroid, Schwarz-Primitive, Schwarz-Diamond. It applies across porosity 70% 90%, considering unit cell fluids. Furthermore, presents effect viscous heating at high Reynolds numbers compares proposed existing ones.
