     On this basis, a novel insight into VOC removal performance of PCO reactors is presented. The key parameter for evaluating PCO reactor VOC removal performance is the number of the mass transfer unit (NTUm), which is shown to be a simple linear product of three dimensionless parameters: the ratio of the reaction area to the cross-sectional area of the flow channel (A*), the Stanton number of mass transfer (Stm), and the reaction effectiveness (η).
     根据该反应器模型,指出评价光催化反应器性能的主要参数NTUm由三个无量纲参数的线性乘积组成,分别是反应面积与流通截面面积的比值(A*),传质斯坦顿数(stm)和反应有效度(η),该三参数分别体现光催化反应降解VOCs过程中的面积因素以及传质一反应过程的影响。

In this paper, the problem of equivalence of a pressurized cavity and a center of explosion in the generation of seismic waves is first discussed. The displacement field caused by an explosion in a spherical cavity situated in a layered medium is then calculated by first finding the impulse response of the medium and then con-volving it with the equivalent point source function.For a homogeneous half space, the transient solution for the displacement of the free surface is determined by three dimensionless parameters...

In this paper, the problem of equivalence of a pressurized cavity and a center of explosion in the generation of seismic waves is first discussed. The displacement field caused by an explosion in a spherical cavity situated in a layered medium is then calculated by first finding the impulse response of the medium and then con-volving it with the equivalent point source function.For a homogeneous half space, the transient solution for the displacement of the free surface is determined by three dimensionless parameters in terms of which the exact solution for the far field is found and the motion near the explosion is also discussed. Finally, the formal solution for the spectrum of the surface displacement caused by a cavity explosion in a layered medium is derived.

本文首先讨论了压力空腔和爆炸中心的等价问题。计算层状介质中的空腔爆炸所产生的位移场时,可先求介质的单位脉冲响应,然后将其与等价的爆炸点源函数做褶积。对于均匀的半空间,自由面位移的暂态解是由三个无量纲的参数所决定的;由此可导出远场位移的精确解。本文也讨论了爆炸点附近的运动。最后还导出多层介质中空腔爆炸所产生的表面位移谱的形式解。

The similarity solutions of a strong shock wave propagation in a mixture of a gas and small solid particles have born investigated. Simiharity solution exists only when the shock is very slrong and the surrounding medium is of a constant density and at rest and with negligible counterpssure. The non-dimensional fundamamental equations are derived and studied. The results depend on three nondimensional parameters;i.e. (i) the ratio of the gas r,(ii)the mass concentraion of the solid particles k, in the mixture...

The similarity solutions of a strong shock wave propagation in a mixture of a gas and small solid particles have born investigated. Simiharity solution exists only when the shock is very slrong and the surrounding medium is of a constant density and at rest and with negligible counterpssure. The non-dimensional fundamamental equations are derived and studied. The results depend on three nondimensional parameters;i.e. (i) the ratio of the gas r,(ii)the mass concentraion of the solid particles k, in the mixture and (iii) the ratio of the densily the solid to that of inilai density of the gas G. Numerical solutions for various values of r, k_p and G are presented and discussed. The speeds of the shock wave front and its location with various energy releases are given.

To check the thermal equilibrium assumption between solid matrix and fluid in porousmedia with internal heat source, the forced convection in channels filled with packed bedswith heat generation was analyzed numerically with the extended Darcy model for flow andthe two energy equations in which the thermal equilibrium assumption is released. Thetemperature difference between the matrix and fluid was dicussed with three dimensionlessparameters (Rep, H/dr and ks/kf). It can be concluded that, one energy equation basedon the thermal equilibrium may be adopted for situations when the conduction of soliddominates over the covection of fluid or when convective heat transfer coefficient bewteenthe two phases is high at large Rep. The variation of Nusselt number at the wall with Repfor differeds ks/kf was also investigated.
