In the foreseeable future, heat exchangers will continue to play an important role in environmental management and have numerous applications, their geometry has been subject of interest for many researchers. The main goal this research is improve exchangers' thermal performance exergetic efficiency using new type nanofluid. concept, effect nanoencapsulated phase change material (NEPCM) addition water producing NEPCM nanofluid transfer augmentation shell tube exchanger (STHE) was investigated, experimentally. Nanocapsules were synthesized by miniemulsion polymerization containing (PCM) as core chitosan (GO/CS) material. After synthesis nanocapsules, nanofluids with different concentration prepared stability thermophysical properties characterized. subsequent stage, exergy efficiencies test conducted on STHE response surface method. experiments performed at conditions; NPCM (φ), inlet temperature (Tin) Re number optimse efficiency. optimum level φ, Tin maximum ɛ (73 %) found be 10.55 %, 78.35 °C 10365, respectively. experimental results demonstrated that proposed could enhance system. It appears a combination gives better cooling rate promising alternative along other techniques.

Abstract Evaluating the concentration of waste discharge across an exponential stretching surface is crucial for its environmental impact. In both ecological and industrial networks, wastewater management crucial. The present study focuses on prevention analysis contamination fluid assets by harmful chemicals. By analyzing these interactions, examines steady, incompressible Casson circulation under influence via a three-dimensional exponentially sheet. thermophoresis, Brownian motion, magnetic field was also examined. Governing equations can be transformed into form ordinary differential utilizing proper similarity operations. These simplified are resolved computationally using Runge–Kutta–Felhberg-45 shooting approach. impacts dimensionless parameters each person’s profile being examined graphs. Furthermore, certain essential engineering coefficients explored. predominant results that in directions, decreases velocities. Buoyancy constraint will increase velocity while thermophoresis contribute to temperature. An 8.04% temperature seen thermophoresis. Skin friction increases with significant parameters, where local pollutant rate mass transmission.

Опубликована: Май 1, 2025

This study investigates the unsteady flow of a hybrid nanofluid (Al2O3+Cu/H2O) over spinning disk in porous medium under influence viscous diffusion, Coriolis force, and magnetohydrodynamics (MHD), following von Kármán swirling model. Slip velocity thermal radiation significantly affect dynamics heat transfer, increasing potential nanofluids for cooling turbine disks jet engines, where protective layer controls boundary through viscosity diffusivity. The novelty this work lies conducting relative sensitivity analysis to test which parameters are most sensitive combined effects magnetic strength, porosity, intensity. governing partial differential equations transformed into coupled nonlinear ordinary using similarity transformations solved numerically value problem fourth-order algorithm (BVP4C). dimensionless range as follows: unsteadiness parameter N: 0.1–0.7, strength M: 0.1–1.9, porosity Λ: 0.1–1, slip λ: 1–2.5, (Rd): 0.1–0.7. Results show that radial momentum profile decreases with Λ λ, temperature rises Rd, axial increases M λ. Response surface methodology (RSM) optimizes M, Λ, Rd better variance yielding R2=95.42% AdjR2=92.36%, confirming model's reliability MHD applications. Relative quantitatively shows is more distribution than Λ.
