The main focus of the present article is the development of a general solution framework for coupled and/or interaction multi-physics problems based upon re-using existing codes into software products. In particular, we discuss how to build this software tool for the case of fluid-structure interaction problem, from finite element code FEAP for structural and finite volume code OpenFOAM for flu...

A dam under seismic excitation contains several multi-physics coupled systems that are of interest in computational modeling. The greatest heterogenous coupled systems are the fluid-structure interaction between the fluid and the dam as well as the fluid and the soil. In addition, there is a region near the dam that is subject to bulk cavitation, where the fluid pressure drops below the vaporiz...

A design has been developed for a rotary fluid coupling to transfer coolant fluids (primarily anhydrous ammonia) across rotating joints of the Space Station. Development testing using three conceptual designs yielded data which were used to establish the design of a multipass fluid coupling capable of handling three fluid circuits. In addition, a mechanism to support the fluid coupling and allo...

Partitioned coupling approaches are an important tool in order to achieve a decent time-to-solution for multi-physics problems with more than two physical fields or changing combinations of fields. We study different approaches to deduce coupling schemes for partitioned multi-physics scenarios, by means of a simple, but yet challenging fluid-structure-fluid model problem. To our knowledge, this...

In this paper, a double-cyclone is used as a gas-solid separator in the fluid bed-drying process to prepare dry HDPE powder from a wet feed of 56000 kg/hr. The quality of dry HDPE depends mainly on particles behavior and flow pattern in the dryer which affect the double-cyclones as an effective equipment in this process. Controlling of the inlet carrier gas causes excellent flow pattern, desire...

In this paper, numerical simulations of coupling phenomena including flow of thermal fluid and heat transfer in solid are performed. To simulate the coupling phenomena, the flow and the heat transfer in solid are computed simultaneously by the solving of the same governing equations in which the flow velocity in the solid region is set to zero. As examples of numerical simulation, the phenomena...
