Studies The Carbon Cigarette Trap Gas Flow Function's Motion Mechanism

At present, the driving force diesel has characteristics of good economic and big power, therefore, it has been widely used as automobile and engineering machinery 's power set etc. But, the diesel contains large amount of feasible particle diesel a important pollution source in becoming a city in exhausting. Technology the technology studying analysis indicates the purification within depending on diesel machine must adopt at the same time to sell the device and the relevance at reduced prices as already being able to not satisfy the above Europe automobile effluent standard III law and regulation request with the fact that the diesel lathes gradually broad application and their effluent standard's gradually strictly . Forecast according to abroad in connection with the expert, the particle fliteration technology will be that particle blow off controls realize a diesel ultimately having most.The main body of the content that priority studies has several parts of the following:(1) Studies fluid flow problem numerical value simulates method in porous medium, such as: under the control of equation numerical value being on the move owing to tradition porous medium simulates method , the method pure fluid of porous medium / coupling flow area numerical value is simulated waits owing to that porous medium model numerical value simulates method , owing to that two-phase method numerical value simulates method.(2) Builds pure fluid of porous medium / coupling area but the porous medium compressing the gas flow characteristic property physics model and mathematic model, and bringing forward decision is hit by fluid two important parameter penetrance and the inertia coefficent admeasurement method of the characteristic property being on the move.(3) Ascertains the required fundamental experiment device parameter and measures parametric amendment, such as: According to the location that static pressure measurement technology demands to ascertain the Guan Zhong length and the static pressure measurement hole , according to measuring range range and whirlpool air pump type etc., and flowmeter numerical reading amendment that the experiment demands to choose flowmeter.(4) Penetrances and inertia coefficent according to the rate of flow He Jing county pressure secretly scheme against porous medium material that the experiment measures and the data handle .(5) Wields the GAMBIT software and the FLUENT software , the porous foam ceramics material flowing into diversity carries out the simulation emulation on the fluid.The sheet thesis is studied originating from the Guang Dong province science and technology government department at the provincial level key scientific and technological projects "vehicle tail gas catches collection and low pressure dispatches the noise elimination integration technology exhausting to study the design studying cigarette catches collection for follow-up carbon mainly by moving mechanism to pure fluid in porous medium provides a basis ".
