Thermal performance comparative analysis of nanofluid flows at an oblique stagnation point considering Xue model: a solar application

Abstract This exploration aims to study the comparison of heat transfer capabilities two nanofluid oblique, steady stagnation-point flow combinations comprising single-walled carbon/water (SWCNHs/water) and multiwalled carbon nanotube/water (MWCNTs/water) toward a stretching surface influenced by nonlinear thermal radiation employing Xue model. envisaged model is inimitable still scarce in literature. Relying on Tiwari–Das model, mathematical framework constructed. The system partial differential equations converted using suitable transformations into an ordinary three equations, which evaluated numerically bvp4c method. physical behavior significant parameters their graphical representation are thoroughly examined. results show that SWCNHs/water outperforms MWCNTs/water nanofluid. It further witnessed SWCNH nanoparticle contained has considerably greater than MWCNT nanoparticles. also validated comparing it with published study.
