A Study on the Effect of Time Delayed Removal during an Accidental Release: Estimation of Crosswind Integrated Concentration with Eddy Diffusivity

Manju Agarwal, Vivek Joseph

Abstract


A study has been made for computing the crosswind concentration during an accidental release of pollutants. Here we consider two dimensional convective diffusion equation with an assumption that during accidental release there is no removal parameter initially in the region of interest but after certain time an artificial removal is introduced in second time interval. Also we consider the eddy diffusivity as a function of downwind distance from the source. These equations are solved with appropriate boundary conditions. The result shows the necessity and importance of removal mechanism and asserts on the emergency preparedness during such a disastrous episode.

We have provided the online access of all issues and papers to the indexing agencies (as given on journal web site). It’s depend on indexing agencies when, how and what manner they can index or not. Hence, we like to inform that on the basis of earlier indexing, we can’t predict the today or future indexing policy of third party (i.e. indexing agencies) as they have right to discontinue any journal at any time without prior information to the journal. So, please neither sends any question nor expects any answer from us on the behalf of third party i.e. indexing agencies.Hence, we will not issue any certificate or letter for indexing issue. Our role is just to provide the online access to them. So we do properly this and one can visit indexing agencies website to get the authentic information.
