Numerical simulations of heat generation, thermal radiation and thermal transport in water-based nanoparticles: OHAM study

Abstract

AbstractThis study investigates the 3D flow properties and heat transfer of copper, titanium/ water nanofluids across a bidirectional surface under the impact of MHD. The thermophysical features of nanofluid are employed using the Tiwari and Das model. Boundary layer theory has simplified the resulting physical principles. By using the proper transformations, the complicated sets of connected PDEs have evolved into ODEs. Equations that have been modify by using OHAM. For various dimensionless component ranges between $$2\le M\le 10$$ 2 ≤ M ≤ 10 .$$0\le a\le 3$$ 0 ≤ a ≤ 3 , $$0.05\le \varphi \le 0.08$$ 0.05 ≤ φ ≤ 0.08 , $$3\le \mathrm{Pr}\le 8$$ 3 ≤ Pr ≤ 8 , $$0\le Rd\le 6$$ 0 ≤ R d ≤ 6 , and $$2\le \lambda \le 4$$ 2 ≤ λ ≤ 4 the results are investigated computationally and graphically. It is observed that fluid parameters improve; they react differently from temperature and velocity profile. Additionally, thermal profiles decrease in comparison to greater Eckert and Prandtl numbers.
