Abstract
The particle interaction method called MPS (Moving Particle Semi-implicit) method has been developed in recent years, which is formulated by represent ing the differential operators in Navier-Stokes equation as the interaction between particles characterized with a kernel function and adopts a mesh-f ree algorithm. This method is suitable especially for treating liquid break up. We extended the MPS method to two-fluid system, introduced a potential- type surface tension, and modified the calculation algorithm to simulate je t flows. The objective of this study is to evaluate the interfacial area (o r, so called binary contact area) of immiscible two-fluid systems with a ch emical reaction, where one is injected as a jet into a pool of the other fl uid. As a first step, we investigated if the proposed method is capable of reproducing the hydrodynamics of jet flow by analyzing Tanasawa's experimen t. In this paper, we describe the formulation and the calculation algorithm of the method, and results of the verification studies.
