A multiphase flow control and heat exchange simulation system

Abstract

This application relates to the field of computational fluid dynamics and system control technology, and discloses a multiphase flow control and heat transfer simulation system, including: a multiphysics tensor modeling module, which reconstructs the control equations into a unified high-order tensor and extracts the curvature tensor; a dynamic tensor dimensionality reduction and implicit coupling solution module, which dynamically reduces the rank of the tensor equations and constructs the tensor product Jacobian matrix; a physical constraint surrogate modeling and transfer optimization module, which constructs a surrogate objective function embedded with physical conservation laws; an asynchronous time stepping and multi-scale coordination module, which realizes asynchronous time advancement and strong coupling solution based on the curvature tensor; and a multi-objective optimization and decision mapping module, which performs multi-objective optimization based on the surrogate objective function. This invention employs a tensor decomposition strategy that reconstructs the multiphysics control equations into a unified high-order tensor and combines it with dynamic rank adaptive adjustment based on the phase interface curvature tensor and the Jacobian condition number, thereby achieving efficient and stable solutions for high-dimensional coupled physical systems.
