Abstract A new optimization algorithm based on a minimum residual technique is introduced to reduce the instability of numerical methods due to using wall functions to specify the boundary conditions for high Reynolds number flows. In the present article, four different models of the wall-function approximation are investigated for separated flow inside a two-dimensional asymmetric straight-walled diffuser. The equations of motion are closed with the κ– $$\varepsilon$$ turbulent model. The spatial discretization of the computational domain is performed using a finite element method, whereas the temporal discretization is based on a semi-implicit sequential scheme of finite differences. The pressure–velocity coupling is solved through a variation of the algorithm of Uzawa. Numerical noise resulting from the symmetric treatment of the convective fluxes is treated via a balance dissipation method. The non-linearities resulting from the wall-function explicit calculation are dealt with by a minimal residual method.

About National Digital Library of India (NDLI)
NDLI logo

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
