The Application of COMSOL Secondary Development Technology in the Fluid-solid Coupling Study of Prionace Glauca Pectoral Fins

Abstract

Abstract. During the cruise process of prionace glauca, its pectoral fins play an important role in keeping balance and stability of its body. The research on the fluid-solid coupling of prionace glauca pectoral fins is of important value to optimizing the design of the AUV and other marine engineering equipment. This paper studies the deformation shrinkage process of coupling between prionace glauca pectoral fins and the flow through the physical field technology of COMSOL fluid-solid coupling, and carries out the secondary development of COMSOL simulation interface to create App, and builds an intuitive user interface which is suitable for the fluid-solid coupling research of prionace glauca pectoral fins. The research result can improve the ability of modelling and post-processing, avoid the user input errors and focus on the output at the same time. The secondary development in this paper provides an important reference for COMSOL in practical engineering application.

Convection influence on ice formation process on the evaporator heat pump pipes

“…The following assumptions are taken into consideration: the ice layer is static and nondeformable, the average ice permeability 10 -12 m 2 , transition interval between water and ice is 1 K. Brinkman, phase change, and heat transfer in fluid equations are used for the calculations in the model [5]. The initial water temperature is 280 K, the boundary temperature for the pipe wall is 263 K. The walls of water container are full isolated.…”
