“…For the simulation of turbulent flow conditions, the Shear Stress Transport (SST) k-omega (k − ω) turbulence model was employed, classified within the Reynolds-averaged Navier-Stokes (RANS) family. This model, which encompasses all modelled turbulence effects [12,13], operates on two key equations. It solves two transport equations, expressed as Partial Differential Equations (PDEs), alongside a storage equation.…”

In the realm of renewable energy, the optimization of solar water heating (SWH) systems stands paramount for addressing the escalating energy demands. This investigation delves into the pivotal role of design configurations in augmenting the efficiency of SWH systems, with a focus on diverse climatic and locational contexts. Employing the k-omega turbulence model within the ANSYS software framework, a meticulous evaluation of three distinct design configurations, namely, tube-over-plate, tube-under-plate, and tube-in-line-with-plate, is presented. The essence of this study lies not merely in delineating the intrinsic characteristics of these configurations but in a comparative assessment of their efficiencies to ascertain the most efficacious design for superior SWH performance. The adoption of the k-omega turbulence model is instrumental in capturing the intricate fluid dynamics that significantly influence SWH efficiency. The findings reveal that the tube-under-plate configuration exhibits remarkable efficiency, while the tube-in-line-with-plate arrangement demonstrates comparably effective performance. These insights represent a substantial contribution to the advancement of water heating technology, paving the way for more effective and sustainable energy solutions.

“…In the solution phase, the solver program conducts matrix formulations, multiplications, and inversions. Central to the CFD methodology is the Navier-Stokes equation, which is based on the principles of mass, momentum, and energy conservation [15]. These governing equations are fundamental to the numerical computations that elucidate the complex fluid dynamics within the heat exchanger.…”

Over recent years, nanotechnology's landscape has witnessed transformative advancements, heralding new research opportunities in scientific and engineering domains. A notable innovation in this evolution is the development of nanofluids, comprising nanoparticles (each under 100 nm in diameter) suspended in conventional heat transfer fluids such as ethylene glycol and water. Distinguished from traditional heat transfer fluids, nanofluids are posited to offer substantial enhancements, particularly in thermal characteristics. The dispersion of nanoparticles, even in minimal quantities, within base fluids markedly improves the thermal properties of these fluids. This study focuses on evaluating the thermal performance of a shell and tube heat exchanger utilizing the shear stress transport (SST) turbulence model. ANSYS CFX, acclaimed for its accuracy, robustness, and expedience in various turbulence models, is employed for this analysis. The SST model is particularly effective in non-equilibrium turbulent boundary layer flows, enabling accurate heat transfer predictions. ANSYS CFX's approach to near-wall equations mitigates the stringent grid resolution requirements often encountered in computational fluid dynamics (CFD) applications. The investigation encompasses the use of water and TiO 2 /water nanofluid at varying concentrations (1%, 2%, 3%, 4%, 5%) in a 3D model and CFD simulation. Enhanced efficiency and cooling performance are observed with the introduction of nanofluids in the shell and tube heat exchanger.
