Coupled Fluid-Structural-Thermal Simulations of Industrial Problems; Requirements, Approaches and Examples - Keynote Lecture

چکیده
The present paper describes some technical and business considerations for the coupled (rather than sequential) simulations of fluid flow, structural, and thermal phenomena in industrial equipment. A Modular (object-oriented) approach of performing coupled simulations is described. The embodying software (MDICE: Multi-Disciplinary Computing Environment) also allows the use of various (interchangeable) engineering analysis codes on a hetroseneous distributed computer environment. This approach offers the highest levels of flexibility and interoperability, and it has much greater potential than the traditional approaches of developing monolithic codes or developing common file formats for data exchange between CFD and CSD codes. Several common examples of thermal stresses at pipe junctions, and the transient loads near closing positions of gate and butterfly valves are presented to illustrate the importance of coupled analyses. All simulations have been performed by using commercial software, viz: CFD-ACE, CFD-FEMSTRESS, MSC/NASTRAN, and MDICE (MultiDisciplinary Computing Environment). INTRODUCTION Why Coupled Simulations?

متن کاملVariable Thermal Conductivity and Thermal Radiation Effect on the Motion of a Micro Polar Fluid over an Upper Surface
The intent of this analysis is to explore the influence of thermal radiation paired with variable thermal conductivity on MHD micropolar fluid flow over an upper surface. The novelty of the present model is to consider the fluid flow along an upper horizontal surface of a paraboloid of revolution (uhspr) with the porous medium. This physical phenomenon is described by a set of coupled...

متن کاملModel Order Reduction for Coupled Problems
In this survey, we provide an overview of model order reduction (MOR) methods applied to coupled systems. The coupling can be linear or nonlinear, weak or strong. Physically, the coupling may come from structurestructure coupling, fluid-structure or fluid-fluid interaction, electro-thermal coupling, electroor thermal-mechanical coupling, or circuit-device coupling. Different MOR methods for cou...
