A numerical study has been carried out to investigate the forced convective flow around a trapezoidal cylinder exposed to a uniform stream of nanofluid. Water-based nanofluid containing various types of nanoparticles (Al2O3, Cu, and CuO) with the solid volume fraction φ varying from 0 to 8% were used to examine the fluid flow and potential heat transfer enhancement from the heated cylinder. Computations based on the finite volume method with SIMPLE algorithm have been carried out at the steady laminar flow regime with a Peclet number range of 25 ≤ Pe ≤ 150. Nanofluids flow and heat transfer characteristics are found to be highly dependent on solid volume fraction, Peclet number, and nanoparticles shapes. Enhanced wake lengths and surface vorticity, reduced drag and higher heat transfer rates are seen in nanofluids. Furthermore, the results reveal that one type of nanoparticle is a key factor for improving some engineering parameters. In particular, the height values of the average Nusselt number Nuav, the maximal surface vorticity ωs, max, and the dimensionless wake length Lr are obtained while using Cu nanoparticles. However, the values of the drag coefficient
are higher for Al2O3 nanoparticles. Eventually, reliable correlations for
,
, and Nuav in terms of φ and Pe have been developed throughout this study.
