“…Design-I produced a thermal efficiency of 94% (7.5% more than Design-II) and a thermos-hydraulic efficiency of 84% (19% more than Design-II). Maithani et al [62] experimentally studied the thermal and friction characteristics of an absorber plate with protrusion of a hemispherical shape by jet impingement. To achieve larger turbulence, the hemispherical protrusions were placed exactly below the impinging jet holes.…”

Jet impingement is considered to be an effective technique to enhance the heat transfer rate, and it finds many applications in the scientific and industrial horizons. The objective of this paper is to summarize heat transfer enhancement through different jet impingement methods and provide a platform for identifying the scope for future work. This study reviews various experimental and numerical studies of jet impingement methods for thermal-hydraulic improvement of heat transfer surfaces. The jet impingement methods considered in the present work include shapes of the target surface, the jet/nozzle–target surface distance, extended jet holes, nanofluids, and the use of phase change materials (PCMs). The present work also includes both single-jet and multiple-jet impingement studies for different industrial applications.

“…Moshery et al [8] proposed an absorber plate with bottom cylinder transverse ribs. Another design of SAC was suggested by attaching hemispherical protrusion and internal conical ring barriers at the absorber plate's bottom [9,10]. Absorber plates having arc-shaped transverse ribs and numerous V-shaped ribs at the bottom was investigated [11][12][13].…”

Jet impingement cooling has been utilized to improve the performance of solar energy technologies such as solar collectors, PV systems, PVT systems, and CPV systems. This article provides an overview of current PVT systems using jet impingement. The distinctions between each study, such as research results and PVT system design, are examined and contrasted. The summary demonstrates that solar collectors are the most widely utilized solar energy technology owing to their direct manufacture. There are 20 solar collector studies, 5 for photovoltaic, 9 for photovoltaic thermal, and 8 for concentrator photovoltaic. Geometric characteristics such as jet diameter, spacing, and nozzle height are critical for maximum performance. Furthermore, numerous kinds of coolant jets, such as air, water, and nanofluid, may be seen from the overview. Hybrid systems, such as PVT or CPVT systems, perform better since they create thermal and electrical energy. As a result, more research into developing the hybrid system is advised.

“…Understanding the function of the micro- and nano-scalar aspects of the hierarchical patterns in the tribological and wetting behaviors is necessary to achieve superior performance [ 73 ]. The surface chemistry and different geometric parameters, pitch (distance between the pillars), height, and diameter of the micro- and nano-features are the factors defining the performance evaluation of different surface textures/patterns [ 78 ]. The tribological and wetting behavior of these features is also influenced by their shape [ 79 ].…”

“…Because the unique interior structure can increase the fracture toughness of the natural materials, the nacre is employed for safeguarding internal soft tissue and the cuticle [ 92 ]. The two-layer structure, which includes a hard layer and a soft layer, has a buffering effect, which helps the skin of desert lizards and sandfish endure wind-blown sand quite effectively [ 78 , 93 ]. The internal vascular system of the skin or bone can provide healing agents to injury sites for self-healing to repair the damage and mitigate further damage [ 94 ].…”

Energy losses due to various tribological phenomena pose a significant challenge to sustainable development. These energy losses also contribute toward increased emissions of greenhouse gases. Various attempts have been made to reduce energy consumption through the use of various surface engineering solutions. The bioinspired surfaces can provide a sustainable solution to address these tribological challenges by minimizing friction and wear. The current study majorly focuses on the recent advancements in the tribological behavior of bioinspired surfaces and bio-inspired materials. The miniaturization of technological devices has increased the need to understand micro- and nano-scale tribological behavior, which could significantly reduce energy wastage and material degradation. Integrating advanced research methods is crucial in developing new aspects of structures and characteristics of biological materials. Depending upon the interaction of the species with the surrounding, the present study is divided into segments depicting the tribological behavior of the biological surfaces inspired by animals and plants. The mimicking of bio-inspired surfaces resulted in significant noise, friction, and drag reduction, promoting the development of anti-wear and anti-adhesion surfaces. Along with the reduction in friction through the bioinspired surface, a few studies providing evidence for the enhancement in the frictional properties were also depicted.
