Computational fluid dynamic analysis of Nodularia Spumigena Microalgae Biodiesel and Karanja biodiesel blends using ANSYS in CI engine

Abstract

Computational fluid dynamics is a fluid mechanics field that utilizes computational modelling and data structures. CFD simulations are being developed as a useful design tool for evaluating the dynamics of engine fluid flow and optimizing over the decades. This research explores the effect of the blending ratio on combustion properties of the CI engine and variables, such as the numerical model, the composition of fuel for simulation models and emissions in CFD analysis using the software of ANSYS FLUENT. The fuel included in the study is diesel, and, 20% mixing with Nodularia Spumigena Microalgae (A20) and Karanja biodiesel (K20) combines Combustion with Diesel. Thermal NOx emissions are comparatively lower with 13.4% and 27.4% for A20 and the K20 blend while compared to diesel. CO emissions are lower with 13.1% and 7.5% for A20 and the K20 blend when compared to diesel. Maximum temperature in the combustion zone drop about 1.76% and 2.64% is observed for K20 and the A20 blend when compared to diesel.
