| Abstract | In order to quantify the performance of a spiral groove thrust bearing at various operating conditions, a two-way fluid structure interaction model with conjugate heat transfer was created. In this model, the fluid passing through the rotating spiral grooves, as well as the fluid passing behind the bearing pads, was modeled with a Reynolds Averaged Navier-Stokes solver that included the effect of turbulence. This fluid simulation was coupled with a structural simulation of the runner and pads that included heat transfer. To simulate the effect of a thrust load, a force was applied to the structural side of the simulation that was, in turn, transferred to the fluid simulation by way of mesh deformation. The resultant data set includes details such as pad motion, temperature, pressure, and film-thickness profiles as a function of applied thrust load. This allows for the determination of the maximum allowable thrust load before contact occurs at some assumed film thickness. This paper outlines the setup procedure and includes a brief discussion of the simulation results. These results demonstrate that it is possible to use fluid structure interaction to predict the load capacity high speed spiral groove thrust bearing. |

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.
