| Abstract | Diethyl ether is one of the potential alternative fuels for the high speed compression ignition engines that can replace the existing neat diesel fuel. It is well known that the combustion characteristic of a compression ignition engine is highly influenced by the fuel spray structure formed during the injection process. In this paper the spray structure formation for the diethyl ether fuel is studied numerically, using the discrete phase model and it is compared with the neat diesel fuel. The spray is investigated in a constant volume chamber maintained at 30 bar pressure. The fuel is injected into the chamber at an injection pressure of 200 bar and 400 bar. The chamber temperatures are maintained at 500 K and 800 K to simulate the vaporizing and non-vaporizing conditions for the spray. The injection duration is for 3 milliseconds. The depth of penetration, the liquid length formed, the Sauter Mean Diameter of the droplets and the distribution of droplets across the spray are studied and compared for the diethyl ether and diesel fuels. The simulated results have shown that the spray penetration and liquid length for the diethyl ether fuel is reduced when compared to diesel fuel at all injection pressures and chamber temperatures. The Sauter Mean Diameter of the ether fuel is found to be decreasing as the injection pressure is increased which is in the similar trend as that of the diesel fuel. |

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.
