Simulation on Gas-Solid Flow with Heat Transfer in Diesel Particulate Filter 査読有り

To reduce particulate matters (PM) including soot in diesel exhaust gas, a diesel particulate filter (DPF) has been developed for the after-treatment of exhaust gas. In simple explanation of DPF, it traps PM when exhaust gas passes its porous wall. However, since the filter would be plugged with particles to cause an increase of filter back-pressure, filter regeneration process is needed. In this study, we have simulated the flow with soot combustion by the lattice Boltzmann method (LBM). Here, the real filter was used in the simulation. The inner structure of the filter sample was scanned by a 3D X-ray CT technique. By conducting tomography-assisted simulation, we obtained local velocity and pressure distributions in the filter, which is hardly obtained by measurements. Especially, to consider the heat transfer to the solid wall of the filter, the equation of heat conduction was solved, simultaneously. That is, the approach for the simulation of gas-solid flow is presented. Based on the temperature change and reaction in DPF, the heat and mass transfer in the filter regeneration process was discussed.

Combustion Characteristics and Flame Structure in a Triple Port Burner 査読有り

G. Okuyama, K. Yamamoto, N. Hayashi, and H. Yamashita

Diffusion flames are widely used in practical combustors such as furnaces and diesel engines. To increase the combustion efficiency and reduce the harmful products to the environments, fundamental researches are needed for improving the design and operation of the combustor. In this study, we have focused on a triple port burner to provide plurality of combustion air jets. The burner consists of three concentric tubes. Air flows in both inner (central) and outer tubes, and fuel (propane) flows in the annulus between these air tubes. Then, two diffusion flames are formed in the boundary of fuel and air streams. We have numerically investigated combustion characteristics in the triple port burner. For comparison, some experiments including the temperature measurement have been conducted. Based on numerical and experimental results, the flame structure has been discussed.

The Numerical Simulation of Fuel-Lean Counterflow Premixed Flame with Flame Curvature 査読有り

N. Hayashi, C. Miyata, H. Yamashita, and K. Yamamoto

The influence of flame curvature and unsteady behavior on the local extinction and flame structure is investigated by numerical simulation of the counterflow premixed flame using chemical kinetics model. To impart a curvature to the flame front, the premixed gas is spouted with axial velocities varying in the transverse direction at the nozzle. The methane-air premixed gas with near flammability limit (equivalence ratio is 0.55) is considered. The heat release rate begins to fall immediately after a part of spout velocity is changed from surrounding
velocity, and the local extinction occurs. However, the flame is recovered by propagating from surroundings. In this study, the flame structures (i.e. heat release rte, temperature and mole concentrations) at this local extinction are investigated, and by comparing with the experimental results by OH-CH2O simultaneous PLIF (Planar Laser-Induced Fluorescence) technique, it is shown that the measurement is the quite useful tool to evaluate the local extinction.
