Abstract

Purpose

Pressure-based methods have been demonstrated to be powerful for solving many practical problems in engineering. In many pressure-based methods, inner iterative processes are proposed to get efficient solutions. However, the number of inner iterations is set empirically and kept fixed during the whole computation for different problems, which is overestimated in some computations but underestimated in other computations. This paper aims to develop an algorithm with adaptive inner iteration processes for steady and unsteady incompressible flows.

Design/methodology/approach

In this work, with the use of two different criteria in two inner iterative processes, a mechanism is proposed to control inner iteration processes to make the number of inner iterations vary during computing according to different problems. By doing so, adaptive inner iteration processes can be achieved.

Findings

The adaptive inner iterative algorithm is verified to be valid by solving classic steady and unsteady incompressible problems. Results show that the adaptive inner iteration algorithm works more efficient than the fixed inner iteration one.

Originality/value

The algorithm with adaptive inner iteration processes is first proposed in this paper. As the mechanism for controlling inner iteration processes is based on physical meaning and the feature of iterative calculations, it can be used in any methods where there exist inner iteration processes. It is not limited for incompressible flows. The performance of the adaptive inner iteration processes in compressible flows is conducted in a further study.

Abstract

Purpose

Although the Daodejing is a text that is more than 2,400 years old, its concepts regarding leadership nevertheless fit well into current discussions on sustainability and responsibility. This paper aims to explore these concepts.

Design/methodology/approach

The paper focuses on the strategic aspects that can be found in the Daodejing's approach to leadership.

Findings

The Daodejing offers interesting perspectives on the relationship between personal development and sustainability. Because of their topicality these concepts are moreover particularly interesting within the context of corporate culture and glocalization for multinational companies operating in China.

Originality/value

The paper explores aspects of the philosophy of the Daodejing that often get neglected, but which offer interesting perspectives on current issues in management.
