“…Numerical simulations were also applied aiming at a better understanding of the inner mechanisms of the mentioned flow regimes, both 2D CFD simulations [45][46][47][48][49][50] and 3D CFD simulations [36,39,[51][52][53][54][55][56][57][58][59]. The transition from the steady flow regimes to chaotic flow regimes was analyzed with detail by Santos et al [41] from PIV experiments in the range of Re-numbers from 100 to 150.…”

For over three decades, opposed-jets reactors have been applied particularly for fast complex chemical reactions where mixing affects the final product distribution. The first opposed-jets reactors, i.e., confined impinging jets (CIJ), had cylindrical geometries. With the advent of microreactors, a new type of prismatic opposed-jets reactors has been introduced, the so-called T-jets reactors. The state of the art of the know-how on mixing in CIJ reactors as well as the current state of the art of T-jets reactors is described. T-jets and CIJ are generally small-scale devices, ensuring that these units can mix fluids within very short mixing times on the order of milliseconds. The small scale has the disadvantage of compromising the reactors' throughput. This fact can prevent the dissemination of this type of mixers to applications where conventional reactors, such as stirred tanks, are used. Attention is paid to the issue on how to scale up opposed-jets reactors without compromising mixing times. A short analysis of the main research questions to be answered in this field is made.

“…To overcome this problem, as suggested by Hosseinalipour and Mujumdar [11], the appropriate number of grids was found through a grid doubling procedure for the ''worst'' case which is with the highest Reynolds number for each geometry; the grid which gave grid-independent result was applied to all other cases with the geometry. This procedure would consume more running time for the lower Reynolds number cases, but it was compensated for in time saving so that there was no need to check grid-independence for each case for a given geometry.…”

“…Hosseinalipour and Mujumdar [11][12][13] developed the first numerical model for two confined plane opposing jets with isothermal boundaries and adiabatic walls in steady laminar as well as turbulent flows, respectively. An extensive parametric study was carried out to study geometric and hydrodynamic effects on the flow and heat transfer characteristics and effects of equal and unequal opposing jets on the flow and heat transfer characteristics.…”

“…Hosseinalipour and Mujumdar [11,12] developed the first numerical model for two-dimensional confined opposing jets with either isothermal or adiabatic walls in steady laminar flow. Temperature at the cross-section was used as a passive tracer to evaluate the mixing characteristics of the system in their works.…”
