摘要

数字计算系统的体系结构决定了一种统一的数学语言的技术基础,用于精确的算术-逻辑描述连续介质力学的现象和定律,用于流体力学和理论物理。计算过程的深度并行化有助于在新的技术水平上复兴函数式编程的应用。计算的效率是由物理和连续介质力学基本定律的真实再现提供的。数值对象和计算操作的张量形式化是为了将流变状态参数和流体力学规律作为数学模型在基本数值单元-大液体颗粒的局部坐标中进行空间插值。该方法允许使用显式数值格式,这是提高由具有自然并行性的数值过程开发的算法效率的重要条件。

Direct computational experiments in fluid mechanics using three-dimensional tensor mathematics
Architecture of a digital computing system determines the technical foundation of a unified mathematical language for exact arithmetic-logical description of phenomena and laws of continuum mechanics for applications in fluid mechanics and theoretical physics. Deep parallelization of the computing processes serves to the revival of application of functional programming at a new technological level. The efficiency of computations is provided by true reproduction of the fundamental laws of physics and continuum mechanics. Tensor formalization of numerical objects and computing operations serves to spatial interpolation of rheological state parameters and laws of the fluid mechanics as mathematical models in the local coordinates of the elementary numeric cells — large liquid particles. The proposed approach allows the use of explicit numerical scheme, which is an important condition for increasing the efficiency of the algorithms developed by numerical procedures with natural parallelism.
