Summary: This study investigates 2D non-Newtonian Sutterby nanofluid flow under the effects of magneto-hydro-dynamics (MHD) over a paraboloid surface, with a focus on the reaction between catalyst and Sutterby nanofluid on the surface causing buoyancy-driven flow in the boundary layer region. The numerical solutions of the dimensionless determining equations are achieved using the Runge-Kutta Fehlberg (RKF) method, with analysis on the influence of Deborah number, Hartmann number, and other parameters on the velocity, temperature, and concentration fields. The study also examines the effects of thermophoresis coefficient, Prandtl number, Brownian motion parameter for the temperature field, and effects of Schmidt number for the concentration field.

Summary: This study investigates the impact of heat and mass transfer characteristics of viscous fluid near a moving wall with transpiration. An exact solution to the unsteady Navier-Stokes equation is obtained. Analytical solutions to the energy and concentration equations are calculated for constant wall temperature near the rare stagnation point, assuming no internal energy change. Influences of transpiration, unsteadiness parameter, Prandtl number, stretching/shrinking wall parameter, and Schmidt number on fluid, heat, and mass transfer features are illustrated graphically and discussed in detail. Two branch solutions for heat and mass transfer phenomena are identified with specific parameter values, which can serve as standard models for numerical code validation.

Summary: This study focuses on the flow of two-dimensional Carreau fluid with heat generation and activation energy over a paraboloid surface, where the effects of key parameters on velocity, temperature, and concentration fields are analyzed numerically and graphically. The results show that the velocity field increases due to the power law index and variable viscosity parameter, while the temperature rises with high heat source parameter values and decreases with Prandtl number. The concentration of fluid increases due to activation energy and thermal diffusivity parameter.

Summary: This study investigates the heat transfer mechanism of nanofluids in two-dimensional non-Newtonian Casson flow on an upper convex surface, accounting for the impact of catalytic surface chemical reactions. The governing equations are solved numerically using RK4 method and Newton's shooting schemes, showing a decrease in temperature profile due to the Casson fluid parameter, and an increase in temperature field due to the chemical reaction parameter.

Summary: Solar energy is crucial due to population growth and global warming, with Parabolic Trough Collectors being widely used for various purposes. The use of helical screw tape inserts in circular tubes can enhance efficiency, and a parametric study revealed optimal values for thickness, helix angle, and inner diameter. Modifying inserts with holes or fins can increase pressure drop slightly, while a tapered-helix design can reduce pressure drop at the expense of decreased Nusselt number. Increasing Performance Evaluation Criteria will be an effective step towards a cleaner environment for Parabolic Trough Collectors.

Summary: The study focuses on the thermal performance estimation of a Parabolic Trough Collector (PTC) for contaminated water purification, showing a high efficiency but with room for further optimization, such as residual chlorine. Results suggest that under specific water flow rate and solar radiation conditions, the temperature and useful heat gain of purified water can reach maximum values.

Summary: Flat-plate solar collectors are a cost-effective technology for water heating in residential buildings. The study focused on sensitivity analysis and optimization of crucial factors in a flat-plate solar collector equipped with twisted tapes, using various soft computing methods. The research found that the efficiency and temperature difference can be optimized by adjusting the friction factor and other parameters simultaneously.
