| Abstract | In the current study, effect of chamber ambient backpressures and temperatures on non-reacting fuel spray characteristics of heavy fuel oil (HFO) under high pressure injection is numerically studied. Four different chamber backpressures ranging from 0.05 up to 2.8 MPa at two different ambient temperatures have been considered in a medium speed engine. An Eulerian-Lagrangian multiphase scheme is implemented to model HFO interaction with air continuous phase by using Open source CFD toolbox of OpenFOAM. Numerical results of fuel spray are validated with good accordance against existing experimental data. Based on the computational findings, enhancement of chamber backpressure results in reduction of temporal spray penetration and increase of spray cone angle at both ambient temperatures. Furthermore, the SMD is found to decrease due to enhancement of chamber backpressures up to 1.4 MPa. Finally, it was found that higher ambient temperature increases the spray penetration length at all chamber backpressures. |

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.
