Abstract We present two numerical experiments concerning application of a recent outflow boundary condition proposal, by Dong et al. (J Comput Phys 261:83–105, 1), to discontinuous Galerkin method (DG) solution of incompressible laminar flows. This new boundary condition (BC) is tailored out for outflow boundaries and its rationale is based on energy influx control at this boundary surface, as described in Braack and Mucha (J Comput Math 32(5):507–521, 2). The authors applied it to various incompressible test-flow examples in a spectral and classic finite-element contexts, and a major result achieved by them was this new outflow boundary’s approach allows us to significantly reduce computational domain size without generating significant errors. Accordingly, due to its already known capabilities and established mathematical basis, it is a natural issue to ask about the DG behaviour over this all-useful achievement. In this work, the DG method is tested in two different flow instances: (1) Kovasznay flow, where convergence rates are measured and (2) laminar incompressible flow around cylinder inside rectangular channel. In this case, drag and lift coefficients are computed, further of the dimensionless Strouhal number. Conclusions are traced to show the readiness of DG to embody this new boundary condition technique.

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.
