The avalanche is simulated using the Savage-Hutter model with Finite Volume Method (FVM) as a numerical solution in one dimension. The scheme used in FVM is collocated-grid. The aim of this research is to observe the avalanche based on different sediment types on the incline bed with the same initial sediment height. These simulations produce the value of velocity and height avalanche. For each type of sediment has a difference in velocity and height of avalanche affected by the internal angle of friction and the bed friction angle. Sediments with the highest bed friction angle have highest speed. The average velocity of each sediment are Quartz with u = 10.627, Yellow Sand with u = 7.437, and Rice with u = 2.1178 at time t = 1.

Unstructured Finite Volume Method

In this paper, a numerical method based on finite volume method for diesel engine is presented. The production of combustion is assumed to be a grey medium and the scatter of particle is neglected. In this paper the unstructured finite-volume method (UFVM) for radiation has been formulated and implemented in an in-house fluid flow solver GTEA. For its comparison and validation of the present FVM on unstructured grids, a test case with 3D complex geometries is chosen, which was used by S. W. Baek et.al.[1]. The results obtained by the presented FVM agree well with the exact solutions. Radiation heat transfer in TBD620 diesel engines is studied with present numerical method. It is shown that the radiation has little effect on average pressure and temperature, but it changes the temperature distribution in cylinder.

It is proposed to study numerically the dispersion of polluting emissions in turbulent conditions around a two-dimensional obstacle. The effect of the presence of obstacles on the flow from a Bent chimney is mainly addressed. A numerical simulation of the dispersion of pollutants emitted by the chimneys was performed using the simulation code. The numerical method used to solve the equations describing the flow is the finite volume method (FVM) and the mesh size adopted is non-uniform, very tight near the stack and obstacle. The results found essentially show that the presence of obstacles modifies the flow.

In this paper, we present an implicit finite volume method for the space fractional Chemotaxis model on a finite domain. Our method is a numerical method which is based on the fractionally-shifted Grünwald formulas. This formula is used to discretisize the fractional derivative. We report several numerical experiments illustrating the efficiency of our method.

In this study, a computational analysis of the distribution of oxynitride concentrations in a tunnel is carried out by using the one-dimentional numerical method for a train-induced unsteady flow. The discretized equations are solved using the finite volume method. The results show that the calculated value and measured one is compatible basically. It can provide a theoretical basis and new idea for design.
