From Rayleigh-B\'enard convection to porous-media convection: how porosity affects heat transfer and flow structure [PDF]
, 2020 We perform a numerical study of the heat transfer and flow structure of Rayleigh-B\'enard (RB) convection in (in most cases regular) porous media, which are comprised of circular, solid obstacles located on a square lattice.

Applications in Energy and Combustion Science, 2023 Ammonia (NH3) is a promising carbon-free fuel but suffers from low flame stability and high NO emission. Moderate or intense low-oxygen dilution (MILD) combustion has been indicated to be a feasible technology for resolving these drawbacks of NH3 during ...

Accretion disk coronae of Intermediate Polar Cataclysmic Variables - 3D MagnetoHydro-Dynamic modeling and thermal X-ray emission [PDF]
, 2017 IPCVs contain a magnetic, rotating white dwarf surrounded by a magnetically truncated accretion disk. To explain their strong flickering X-ray emission, accretion has been successfully taken into account. Nevertheless, observations suggest that accretion

Evolution of "51Peg b-like" Planets [PDF]
, 2002 About one-quarter of the extrasolar giant planets discovered so far have orbital distances smaller than 0.1 AU. These ``51Peg b-like'' planets can now be directly characterized, as shown by the planet transiting in front the star HD209458.

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

European divertor target concepts for DEMO: Design rationales and high heat flux performance
Nuclear Materials and Energy, 2018 The divertor target plates are the most thermally loaded in-vessel components in a fusion reactor where high heat fluxes are produced on the plasma-facing components (PFCs) by intense plasma bombardment, radiation and nuclear heating.
