Selective Catalytic Reduction (SCR) is one of the most promising technologies for reducing after-exhaust NOx emissions. Cu zeolites generally provide high SCR conversion rates at temperatures ≤ 350◦C. The limitations associated with powdered catalysts, such as low mass diffusion and high pressure drop, can be minimized to a certain extent by replacing them with structured catalysts. The foam catalysts exhibit superior characteristics, such as a high surface-to-volume ratio, porosity, and tortuosity, which improve the mass diffusion and lower the pressure drop.

The present study focuses on experimental techniques to understand the self-excited oscillation characteristics in low-density round for fully developed and turbulent flow conditions, as well as rectangular jets, and study the effects Reynolds number, momentum thickness, density ratio and aspect ratio on self-excited oscillation. Two global modes exist in low-density round jets. The results confirms that oscillations in low-density round jets are axisymmetric irrespective of S and D/θ, and turbulent jets can exhibit self-excited oscillations for S ≤ 0.53.

Protostellar jets are fossil records of the accretion history of protostars. Studying these jets opens up an indirect window of knowledge into the evolutionary stages and activities of the protostar, the direct study of which is difficult due to its highly embedded nature. The research highlights a theoretical and observational study of protostellar jets in radio and near-infrared wavelengths, respectively.

N-Dodecane plays a crucial role in surrogate fuels for gasoline and jet fuels. Selecting the right surrogate fuel combination depends on the properties of its individual components. Precise reaction mechanisms are essential to predicting combustion characteristics, including laminar burning velocity and ignition delay times. Unfortunately, data for n-dodecane-air, oxy-n-dodecane with diluents like N2, CO2, H2O, and n-dodecane-H2-air are scarce in the literature. This study aims to bridge this gap.

Transitional flows with an unsteady inflow play a vital role in a broad range of applications, including biological fluid transport to space applications. In such cases, the thickness of the boundary layer formed over the solid surface varies in both space and time, causing a high level of complexity in the path of vortical structures formed from the shear/boundary layer. Also, time and space-dependent shear stress exerted by the fluid, separation, and associated instability phenomena are to be better understood.
