Energy conversion efficiency improvement studies on unconventional premixed micro-combustors partially inserted with porous medium
TL;DR: In this paper, T-and Y-shaped micro-combustors partially inserted with porous medium (PM) are both experimentally and numerically investigated, and the results show that the radiation efficiency ηE of the double-channel microcombustor is higher than that of the single-channel under the same working condition.

NOx emission and energy conversion efficiency studies on ammonia-powered micro-combustor with ring-shaped ribs in fuel-rich combustion
TL;DR: In this paper, three micro-combustors with different ring-shaped ribs in a cross-sectional view of 1) rectangular, 2) Ո-shaped and 3) ǫ-shaped are proposed and fuelled by NH3, and extensive numerical comparisons are made with 3D models built by structured mesh.

The effect of embedded objects on pool fire burning behavior
TL;DR: In this paper, the influence of a thermally conductive object on the burning behavior of a hexane pool fire using a validated numerical model was analyzed using two segments: a one-dimensional model that solved the transient heat transfer in the cylinder and a transient two-dimensional scalar transport equation that solves the temperature field inside the fuel region.

Experimental study of flame characteristics and stability regimes of biogas – Air cross flow non-premixed flames
TL;DR: In this paper, the stability of cross-flow non-premixed flames is studied systematically, where biogas is injected through a horizontal porous plate and air is blown parallel to the fuel injector.

The Film Combustion of Liquid Fuel
TL;DR: In this article, the authors examined and partially solved the problem of controlling the rate of combustion in large droplets, where the heat transfer and diffusion processes will have removed the chemical reaction zone far enough from the droplet to where it is less sensitive to the effects of the droplets itself.

Experimental and numerical investigation on combustion characteristics of premixed hydrogen/air flame in a micro-combustor with a bluff body
TL;DR: In this article, the effects of the inlet velocity and equivalence ratio on the blow-off limit, combustion efficiency and exhaust gas temperature were examined in a planar micro-channel with a bluff body.

Effect of bluff body shape on the blow-off limit of hydrogen/air flame in a planar micro-combustor
TL;DR: In this article, the effect of bluff body shape on the blow-off limit was investigated with a detailed H 2 /air reaction mechanism, and the results showed that the blowoff limits for the triangular and semicircular bluff bodies are 36 and 43 m/s respectively at the same equivalence ratio of 0.5.

Buoyancy effects on horizontal boundary-layer flow and heat transfer
TL;DR: In this article, the conditions under which there are significant effects of buoyancy on a forced-convection, boundary-layer flow along a flat plate were determined and it was found that lowPrandtl number fluids are more sensitive to buoyancy effects.
Experiments concerning the mechanism of flame blowoff from bluff bodies
TL;DR: In this article, a simple formulation of the similarity conditions was obtained in which the fluid mechanical parameters and chemical parameters were effectively separated. But the results indicated that a relatively simple formulation was not sufficient to handle the complexity of the flame holding mechanism.
