Boundary Treatments

Advances in computational aeroacoustics (CAA) depend critically on the availability of accurate, nondispersive, least dissipative computation algorithm as well as high-quality numerical boundary treatments. This paper focuses on the recent developments of numerical boundary conditions. In a typical CAA problem, one often encounters two types of boundaries. Because a finite computation domain is used, there are external boundaries. On the external boundaries, boundary conditions simulating the solution outside the computation domain are to be imposed. Inside the computation domain, there may be internal boundaries. On these internal boundaries, boundary conditions simulating the presence of an object or surface with specific acoustic characteristics are to be applied. Numerical boundary conditions, both external or internal, developed for simple model problems are reviewed and examined. Numerical boundary conditions for real aeroacoustic problems are also discussed through specific examples. The paper concludes with a description of some of the much-needed research in numerical boundary conditions for CAA.

The Relationship

Purpose – The purpose of this paper is to investigate the boundary conditions in the relationship between feedback-seeking behavior (FSB) and work performance. The authors hypothesized that the positive influence of employees’ FSB on their work performance is influenced by perceived quality of feedback. The authors also expected that employees’ trust in their supervisors moderated the interaction between their FSB and perceived feedback quality. Design/methodology/approach – Data were collected from 202 employees in South Korea. A hierarchical multiple regression analysis was performed to test the hypothesis. Findings – The results showed that while employees’ FSB was positively related to work performance, the influence was stronger for employees who perceived they were receiving high quality of feedback from supervisors. The authors also found that the moderating effect of feedback quality on the relationship between FSB and work performance was stronger when employees had high levels of trust in their supervisors. Practical implications – The findings suggest that if managers wish to encourage employees to achieve work goal and desirable performance levels by actively engaging in FSB, they should pay more attention to providing high quality of feedback and building trust with employees. Originality/value – This study contributes to expand the understanding of FSB-work performance relationship by verifying the boundary conditions, which suggests the importance of examining the moderating factors in the FSB mechanism.
