Title

DISCRETIZATION OF FLOW CONTAIN NITRATE IN POROUS MEDIA BY FINITE VOLUME TECHNIQUE

Pages

  317-324

Abstract

 One of the most important pollutants of groudwaters is NITRATE. Different human activities including the application of chemical fertilizers in agriculture, causes the emission of NITRATE into groudwaters. In this paper, the dynamic effect of soil moisture on carbon and nitrogen cycles has been analyzed by presenting a connection between soil moisture sample and nonlinear differential equations. At present, wide researches are carried out on modeling soil moisture control in solution flows contain NITRATE. In order to do so, separation of energy conservation law equations is carried out by a particular method. The mathematical model governing the NITRATE containing current in non-isotropic environment has been presented in the form of combined equations. Equation for distribution in multiple environments and Darcy rule has been considered in this model. Then, using FINITE VOLUME method, separation of flows contain NITRATE in POROUS MEDIA is carried out. The current flux is obtained from central difference approximations or UPWIND approximation. Mashad plain has been considered for case study at this research. Carrying out calibration operation, the measured results have been contrasted with numerical results of FINITE VOLUME method. After testing the model, it is possible to foresee the way of NITRATE changes in other nodes of calculation network. Using these forecasts, the quality of drinking water for several next years is determined. Carrying out numerical modeling by FINITE VOLUME method, it is found out that the quality of drinking water of Mashad plain would be suitable for the next ten years.
