Novel Cu-MXene hybrid nanofluids for the experimental investigation of thermal performance in double pipe heat exchanger

Scientific Reports, Journal Year: 2025, Volume and Issue: 15(1)

Published: March 22, 2025

Abstract This work aims at analyzing the performance of a double-pipe heat exchanger (DPHE) using low concentrated (0.02–0.06 vol%) water, methanol, castor oil and silicon based Cu-MXene hybrid nanofluids. Convective transfer experiments were successfully performed in fabricated modular double pipe without any twisted tapes, surfaces effectively measured various parameters such as Nusselt number (Nu), coefficient (h), rate (Q), overall (U), friction factor ( f ), pressure drop (∆P), thermal (TPF). The results indicated considerable improvement Nu, h, U with some penalty ∆P. Moreover, TPF value methanol water-based nanofluids exceeded unity showed superior characteristics, confirming viability improving DPHE. Eventually, LMTD positively validated Aspen HYSYS 12.1 version software to verify experimental variation less than ± 5.35% for LMTD. These demonstrate possible usage proposed management systems, automotive cooling, industrial cooling respectively. In addition, these findings also encourage its use cost-effective technologies.

The present experimental study investigates the thermal and hydraulic performance of Ethylene Glycol (EG)-based ZnO nanofluids (NFs) in circular minichannel test sections, each 330 mm length 1.0-2.0 inner diameters. experiments were conducted under steady-state constant heat flux laminar flow conditions. stable ZnO/EG-based NFs synthesized using a standard two-step method varying nanoparticles (NPs) loadings (0.012-0.048 wt%). morphological characteristics, crystal structure, specific surface area (SSA) showed that NPs sized nm, possessing excellent structure enhanced area. Thermal conductivity (TC) viscosity (VC) examined 20-60 °C temperature range. Both TC VC possessed an increasing trend with rise concentration NPs. However, rise, increased while decreased vice versa. highest enhancements 14.38 % 15.22 %, respectively, at 40 0.048 wt% loading. enrichment recorded local average transfer coefficient (HTC) 14.80 13.48% 1.0 diameter, respectively. It was directly proportional to loading volume rate NFs. friction factor also section's cross-sectional area, pressure gradient inverse behavior.

Impact of chemical reaction on hybrid nanofluid (GO + MoS₂) flow over an exponentially stretching sheet with Soret and Dufour effects

Asia-Pacific Journal of Chemical Engineering, Journal Year: 2024, Volume and Issue: 19(4)

Published: April 11, 2024

Abstract The Soret and Dufour effects play a crucial role in various fields such as geosciences, groundwater pollutant migration, chemical reactor operations, binary alloy solidification, isotope separation. This study focuses on examining the impact of mixed convective flow hybrid nanofluid through an exponentially stretching sheet with effects. is affected by factors like variable viscosity, radiation, viscous dissipation, activation energy. Instead no‐slip condition at boundary, velocity slip, thermal concentration slip are considered. physical problem modeled using boundary layer theory, patterns expressed partial differential equations (PDEs). These governing fluid transformed into non‐linearly coupled ordinary (ODEs) exponential similarity transformations. simplified ODEs resolved MATLAB bvp4c package. parameters velocity, temperature, illustrated figures. Additionally, drag force coefficient heat mass transfer rates calculated for presented graphically tabular form. It observed that compared to nanofluids, nanofluids increases up 21.05% solute buoyancy ( δ ). Also, rate can be increased .96% reaction σ m A comparison this work previously published research has been reported.
