Improvement in sealing effectiveness of air curtains using positive buoyancy
Tanmay Agrawal, Narsing K. Jha, Vamsi K. Chalamalla
Air curtains are commonly employed in building applications to facilitate aerodynamic sealing against the exchange flow that occurs through an open doorway due to the density diffe…
Elastically driven Kelvin-Helmholtz-like instability in planar channel flow
Narsing K. Jha, Victor Steinberg
Kelvin-Helmholtz instability (KHI) is widely spread in nature on scales from micrometer up to Galactic one. This instability refers to the growth of perturbation of an interface be…
Universal coherent structures of elastic turbulence in straight channel with viscoelastic fluid flow
Narsing K. Jha, Victor Steinberg
In the present study, we investigated flow structures and properties of elastic turbulence in straight 2D channel viscoelastic fluid flow and tested earlier observations. We discov…
Contaminant transport by human passage through an air curtain separating two sections of a corridor: Part II -- two zones at different temperatures
Narsing K. Jha, D. Frank, L. Darracq +1
Air curtains are installed in open doorways of a building to reduce buoyancy-driven exchange flows across the doorway. Although an air curtain allows an unhampered passage of human…
Contaminant transport by human passage through an air curtain separating two sections of a corridor: Part I -- uniform ambient temperature
Narsing K Jha, D. Frank, P. F. Linden
Air curtains are commonly used as separation barriers to reduce exchange flows through an open-door of a building.Here, we investigated the effectiveness of an air curtain to preve…
