Effect of using insert on the flow pressure in cylindrical silo

1 Introduction The use of cylindrical silo with discharge hopper is widespread in many industries, in which materials are stored and processed until they are used in industry. Finding the dynamic flow pressure produced on the wall and the hopper of a silo during filling and discharging is one of the most important stages when designing silo and operating it safely. [ 3 ] In addition to that, the type of flow patterns produced in the silo has a significant effect on the distribution of flow pressure exerted on the silo wall and hopper. It has been agreed that

Numerical solution through mathematical modelling of unsteady MHD flow past a semi-infinite vertical moving plate with chemical reaction and radiation

number 𝜇 Dynamic viscosity 𝜌 Density 𝜔 Very small numerical number F(t) Function of t 𝜑 1 Volume fraction m Effective magnetic number 1 Introduction Magnetohydrodynamics (MHD) is concerned with the study of the interaction between magnetic fields and fluid conductors of electricity. The body force acting on the fluid is the Lorentz force that arises when electric current flows at an angle to the direction of an impressed magnetic field. Due to increasing applications of MHD, researchers have been attracted to study the various types of flow

NUMERICAL MODELING OF VERTICAL WELLS IN UNSTEADY GROUNDWATER FLOW CONDITIONS

Abstract

This article presents the results of numerical calculations of drainage of a large engineering construction - “Afrykarium” in Wrocław ZOO, Poland, based on a 2D numerical model for seepage flow. In the numerical simulations the real (natural) hydrogeological conditions, water-courses, surface reservoirs and time dependent seepage flow (during drainage) are taken into account. The aim of numerical calculations was to determine quantities (draining time, number of wells, spacing and arrangement of wells, flows for every well, and hydraulic head map) necessary to design an effective drainage system of construction site. The mathematical model adopted to illustrate and predict groundwater depression during pumping was the Boussinesq equation for unsteady 2D flow.
