Numerical Investigation of Air Entrainment and Outlet Temperature Characteristics of a Convex-Type Infrared Suppression Device

Sachin K. Mishra, Ashok K. Barik
Journal: ASME Journal of Heat and Mass Transfer
Publisher: ASME
Article Type: Research-Article
J. Heat Mass Transfer. December 2022, 144(12): 122102.
Paper No: HT-22-1034
https://doi.org/10.1115/1.4055517
Published Online: September 29, 2022
... IRS device has been proposed consisting of five numbers of the convex-type funnels. The air entrainment ratio has been numerically computed by solving the transport equations (i.e., mass, momentum, energy, turbulent kinetic energy, and its dissipation rate in a structured grid arrangement by employing...
