Abstract This paper explores a computational approach to model multiphase heat transfer and fluid flow in natural circulation loop utilizing nanofluids. We propose implement an Euler–Euler framework CFD environment, incorporating innovative boundary condition preserve mass conservation during thermophoretic particle flux. The model’s accuracy is verified through one-dimensional example, by comparing results against both Euler–Lagrange in-house finite volume solution. Experimental validation conducted with aluminum oxide nanofluids at varying nanoparticle concentrations. prepared the measured their thermophysical properties up $$60^\circ$$ 60 ∘ C. assess thermal performance of nanofluid different heating powers via experiment numerical simulations. findings reveal that enhancement offered modest, minimal differences observed between proposed simpler single-phase model. underscore while offers detailed particle–fluid interactions, its practical advantage limited this context.
