Deploying Open Source Acausal Modelling Software in Teaching Vehicle Dynamics Course A. J. D. Nanthakumar, M. Leenus Jesu Martin, R. Rajendran Computer Applications in Engineering Education, 2025 The present day economic scenario and market conditions has necessitated the importance of Science, Technology, Engineering and Mathematics (STEM) education to be industry oriented and interdisciplinary. This requires a rigorous curriculum coupled with pro active engagement of student learners. The engineering industry has adopted modelling and simulation technique for many of the apparent benefits including less time to market and reduced product development costs. In such a state of affairs, STEM courses pertaining to modelling and simulation are quintessential. The presented paper explains about the pedagogical exercise carried over in the Vehicle Dynamics course conducted for the final year Automobile Engineering students. The students were introduced to Acausal modelling approach for two fundamental exercises—single degree of freedom system, quarter car model—conducted for the laboratory sessions of the Vehicle dynamics course. The acausal modelling approach was compared with causal modelling approach which had been the widely deployed modelling technique. Matlab Simulink software was utilized for causal modelling and the open source platform OpenModelica was utilized for acausal modelling. Simulink/Simscape library was also utilized for comparison. The modelling time has reduced by 20%–37.5% for single degree of freedom system and by 10%–60% for quarter car model in acausal modelling approach. Most of the students agreed in a survey about the ease and simplicity when using acausal modelling technique when compared with causal modelling technique.
Combined effects of various strategies to curtail exhaust emissions in a biomass waste fueled CI engine coupled with SCR system V. Praveena, M. Leenus Jesu Martin, V. Edwin Geo Engineering Science and Technology an International Journal, 2022 This study is an exhaustive investigation on engine performance and combustion features of a conventional diesel engine charged with biodiesel produced from biomass waste. Grapeseed oil methyl ester resulted in poor thermal efficiency with enormous quantity of harmful emissions. As an effort to reduce the engine pollutants, Grapeseed oil methyl ester was doped with zinc oxide nano particles, engine cylinder shape modification and exhaust gas recirculation method was used. Hydrocarbons, carbon monoxide and smoke emissions reduced considerably, whereas reduction in nitrogen oxide emissions was low. Selective catalytic reduction technique at optimized mass flow rate of aqueous urea solution minimized the nitrogen oxide emissions by 76.9% compared to grapeseed oil methyl ester without compromise in brake thermal efficiency.
