“…Their results of basin water and glass temperatures of the present study were compared with the experimental measurements with maximum errors for basin water and glass temperatures are 4.35% and 2.87% respectively. Rashidi et al [62] proposed a VOF model by utilizing ANSYS-FLUENT investigate the potential of Al 2 O 3 -water nano-fluid to improve the productivity of a single slope SS. They utilized VOF model to simulate the evaporation and condensation phenomena in the SS for two dimensional model utilizing FVM.…”

a b s t r a c tComputational fluid dynamic (CFD) is a simulation tool which utilizes the applied and computational mathematics for fluid flow regimes modeling to predict the heat, mass and momentum transfer behavior. In recent years, the solution's accuracy of the CFD simulations became within the acceptable range demonstrating that CFD is a valid tool for performance analysis and design development for many thermal-hydraulic systems. This encourages researchers to use it in the modeling of evaporation and condensation phenomena or two-phase flow with a vapor-liquid phase change process and mass and heat transports through the interface simulation which is one of the urgent difficulties in the solar stills development and analysis. The aim of this is to introduce a comprehensive review work of the highlights that have been made through the recent years for most important studies about the CFD approach as a tool for performance prediction and analysis in addition to design improvement and development for solar stills. This study is supported with a compact synopsis in the form of, computational domain (two or three dimensional), CFD software utilized, operating and geometrical parameter range, simplified assumptions and the better CFD results.

Summary This work aims at augmenting the amount of potable water using MgO and TiO2 in stepped solar still. Experiments were carried out for the climatic conditions of Chennai, India, with two different concentrations of nanofluids inside a stepped basin under three different cases. Results show that there is an improvement in yield of fresh water from stepped solar still by 33.18% and 41.05% using 0.1% and 0.2% volume concentration of TiO2 nanofluid, respectively, whereas the freshwater yield from stepped still with MgO nanofluids improved by 51.7% and 61.89%. Furthermore, the economic analysis revealed that the cost of potable water from the modified solar still reduced from 0.029 to 0.016 $/kg. Similarly, the useful annual energy, yearly cost per kilogram, and annual cost per kilowatt hour are significantly profitable with the use of MgO nanofluid in the stepped basin and found as 512.46 kWh, 0.025 $/kg, and 0.026 $/kWh, respectively. It is also found that the cost of potable water from the modified still significantly increases as the amount of fresh water produced is decreased with increased fabrication cost of the solar still.

A speculative investigation has been presented to explore the salient features of magnetohydrodynamic (MHD) Prandtl-Eyring nanofluid over stretching surface. Effects of Navier slip and convective boundary conditions are included in flow configuration. The effects of higher order chemical reactions along with Nield conditions are assumed in the concentration of nanoparticles. The mathematical modelling of the said flow problem accomplished the nonlinear partial differential equations along with appropriate boundary conditions. The nondimensional form of governing problem is yielded with the aid of similarity variables. The pivotal physical quantities, ie, velocity, temperature, and concentration (in nondimensional form), within boundary layer region are computed with shooting technique. The physical significance of flow controlling parameters on velocity, temperature, and concentration is illustrated through graphs. Additionally, thermophysical aspects of fluid near stretching surface (wall friction factor, wall heat flux, and wall mass flux) are instantiated graphically. A comparison of the current solution with reported data is established to validate the accuracy of adapted procedure. It is observed that the current findings agree with existing data. This led to confidence on adapted numerical procedure.
