“…The location of the maximum Nu was observed to be insensitive to the Reynolds number. Pratap et al [74] performed a numerical study to analyze the impact of impingement height, using nanofluids, on heat transfer performance through a circular confined jet. The non-dimensional jet-target plate spacing (H/D) ranged from 2 to 10.…”

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.

“…They found that the G j / D j reduction increased the values of heat transfer coefficient ( h ) and Nusselt number ( Nu ). Pratap et al 32 studied the effect of impingement height on heat transfer enhancement with a circular confined impingement jet using nanofluids. It was observed that Nu was maximum when nanofluids were used, as compared with water.…”

A numerical study of a three-dimensional, turbulent, forced convection flow around a hot cubic block exposed to cross-flow and an impinging jet is carried out. The standard k-ε turbulence model is used to study the effects of Reynolds number ratio on the flow and heat transfer. For each value of the Reynolds number of the jet, the Reynolds number ratio is equal to 1, 1.5, and 2. The influence of the channel height and the jet axis location are also examined. The governing equations are solved by using Ansys Fluent software 14.5. Results show that the heat transfer increases with the increase in the Reynolds number ratio. At the top of the cube, better cooling occurs with an increase in the speed of the impinging jet. A reduction in the height of the channel and the displacement of the axis of the jet toward the channel inlet improve the heat transfer. Our simulations are compared with experimental data found in the literature, using different turbulence models.
