This paper presents an analysis of viscous fluids and a Rivlin–Ericksen (R‐E) viscoelastic fluid interface under the influence of heat and mass transfer, while both fluids are exposed to an axial electric field. The fluids are restricted within an annular region that is enclosed by two rigid cylinders. The outer section of the annular region holds the R‐E viscoelastic fluid, while the inner section is filled with the viscous fluid. To ascertain the correlation between perturbation growth and wavenumber, the theory of potential flow on viscoelastic–viscous fluids is applied, and the result is represented as a second‐order polynomial. This correlation is numerically solved using the Newton–Raphson method. Variables of viscous flow, such as electric field strength, heat transfer coefficient, viscoelasticity, viscosity, and so forth, are numerically studied. With an increase in electric field strength, the perturbation growth decays and expands for the particular combinations of permittivity and conductivity ratio, showing the dual effect of the axial electric field.

The manuscript is written for flow escalation based on an experimental data for a Solar Assisted Heat Pump Water Heater (SAHPWH) increasing building energy efficiency. For the investigation, a Solar Assisted Heat Pump (SAHP) was conceived, manufactured, and tested in real time. The findings of the experiments shows that single glazing with average sun radiation of 600–750 W/m2, COP of approx. 6 can be obtained with identical heat gains. This study shows that when a flat plate collector of area 1.83 m (L) × 1.22 m (W) × 0.1 m (T) with a 0.5-mm-thick black copper plate absorber with clear glazing as a cover receives average radiation of 700 W/m2, then setup can supply 60 litres of water for residential use from 15 °C to 45 °C in approx. 70 min. In addition, the study finds that the collector efficiency factor F’ is likewise shown to have a direct connection with the absorber and an inverse relationship of tube spacing. The findings indicated that the technology has significant commercial potential, particularly in sectors such as with solar resources for improving building energy efficiency.

Energy demand has grown rapidly with increase of global population. Surge in energy consumption is mainly driven by both economic and technological advancement. The conventional fossil fuels sources (coal, oil, and natural gas) and nuclear energy are depleting in nature known as non-renewables. Burning of fossil fuels contribute significant amount of greenhouse gases emissions, which negatively impact the global ecosystem. Access to energy is essential for modern civilization, yet we must seek alternative energy sources to protect our planet by controlling the emissions. Capturing harmful Green House Gases (GHG) with the help of advanced technologies helps reduce the risk to some extent. However, alternative energy sources must be renewable and sustainable. Renewable energy resources vary by geographical location and include solar, wind, hydro, and bioenergy, among others. The most appealing primary benefits of renewable energy include its low environmental impact, consistent availability even in challenging weather conditions, and its effectiveness in reducing pollution. Additionally, renewable energy contributes to economic growth, fosters job creation, and enhances energy security. However, there are challenges associated with renewable energy storage, which scientists are actively working to address. In addition, public opposition for the installation of renewable energy infrastructure also create difficulties. Increasing public education and awareness regarding the advantages of renewable energy can assist increasing the acceptability, which can further help policymakers in making well-informed decisions. This paper provides a comprehensive overview of diverse renewable energy sources and their current advancements in development. This review further finds that effective government policies aimed at reducing carbon emissions, coupled with improved technology and storage solutions, the adoption of renewable energy will expand significantly in the coming years.
