Abstract
This paper reports on the development of combination analysis of a three-dimensional fluid dynamics and structure around a mixing valve with SMA (shape memory alloy) coil. A mixing valve with SMA coil automatically controls the mixed water temperature with SMA coil. However we can not simulate the phenomenon with a simple computational fluid dynamics, because the movement of valve brings the transition of fluid shape. Furthermore it is a nonlinear phenomena such as vibration of the valve. We calculated one problem to test this module. We described the whole aspect of combination analysis of fluid dynamics and structure and present the results of this calculation.
