NUMERICAL SIMULATION OF FLUID-STRUCTURE INTERACTION BETWEEN FISHING WOBBLER AND WATER

This paper deals with modeling, discretization, and numerical analysis of the two-way fluid-structure interaction between a fishing wobbler and a water stream. The structural domain is an assembly of several bodies that have multiple mutual structure-to-structure interactions. These interactions are mostly nonlinear contacts that significantly influence the time step used in simulations. As a result of these nonlinearities, the numerical solving of such a model requires significant computer resources and a long computational time. The paper also presents the creation and numerical simplifications of the model. However, the model remains very realistic. It is concluded that solving the structural domain in a model that retains the interaction between solid bodies is more computationally sensitive and more demanding than solving the fluid domain.

Architectural Modeling Design based on Reciprocal Structure

The innovation of this research is to build connection between the traditional reciprocal structure and the contemporary architectural modeling design. The purpose of this reasearch is to explore the design method of architectural modeling based on mutual structure. Firstly, the reciprocal structure is classified according to the multi-dimensionality of the construction mode.Secondly, the relationship between the mutual structure and the architectural modeling is explained. Finally, the three factors affecting the architectural modeling on the basis of mutual structure are summarized: 1) morphology; 2) interface; 3) space, and then from these three layers to present the shaping method.
