Flow Through

In this paper, the natural fiber which has been used was jute fiber as the materials for the vacuum infusion. The process that will be using in this experiment is Vacu-um Infusion Process (VIP). There are three specimens which will be conducted in this thesis which consists of five layers. The specimens are Fiberglass, Hybrid Fiber and Natural Fiber. The mathematical analysis of resin flow through a fiber pre-form is based on the theory of (viscous) flow through porous media, which was formulated by Darcy. So, the permeability will be determined by using Darcy’s law equation and came out with the graph of the experiment. The result indicated that the jute fiber is having the constant and high value of permeability.

New Treatment

The present article is a contribution to the study of unsteady, nonlinear, Darcy flow through porous media by use of a finite element approximation. Many mathematical models proposed assume that the acceleration is small and has nearly the same orientation as the velocity. Those hypotheses seem to be debatable in breakwater studies. A new treatment of the relevant equations is presented and the determination of the free surface is made by the residual flow scheme.
