It is shown that cubic spline method is effective for restraining numerical dispersion in numerical simulation of hydrodynamic dispersion equations with radioactive decay.
The results show that hydrodynamic dispersion and indigenous biodegradation under mixed electron accepter conditions are primary mechanisms for the attenuation of ethanol and BTEX in porous media.
The breakthrough curves for heavy metals of solidification sludge were obtained by flexible-wall permeameter and the hydrodynamic dispersion parameters were acquired by genetic inverse method.
采用柔性壁渗透仪获得了固化污泥中重金属的穿透曲线,并采用遗传算法反演了固化污泥的水动力弥散参数。
In that case, it is significative that the research which is about hydrodynamic dispersion with the effect of metro trains vibration.
Under certain conditions, the effect of hydrodynamic dispersion is relatively weak, so that an abrupt interface approximation can be used in studying seawater intrusion in coastal aquifers.
