Effect of pressure and turbulence intensity on the heat flux during flame wall interaction (FWI)
Flow, Turbulence and Combustion, 2023 Abstract Combustion applications such as IC engines are a major source of power generation. Renewable alternative fuels like hydrogen, ammonia and efuels promise potential of combustion in future power applications. Most power applications encounter flame wall interaction (FWI) during which high heat losses occur. Investigating heat loss during

Hurricane's maximum potential intensity and surface heat fluxes
, 2018 Emanuel's concept of Maximum Potential Intensity (E-PI) relates the maximum velocity $V_{\rm max}$ of tropical storms, assumed to be in gradient wind balance, to environmental parameters. Several studies suggested that the unbalanced flow is responsible for E-PI sometimes significantly underpredicting $V_{\rm max}$.
