Dear All, Greetings from ESMOC 2024- 4th Energy System Modeling and Modeling Conference! ESMOC creates a forum for interactions on all energy issues. The first ESMOC (ESMOC 2013) was held at NIT Durgapur in December 9-11, 2013, 2nd ESMOC (ESMOC 2017) at NIT Durgapur in December 11-13, 2017 and 3rd ESMOC (ESMOC 2021) December 5-7, 2021.This international meeting mainly focuses on the modeling and experiments related to nuclear energy, petroleum energy and thermal energy. We welcome both theoretical and experimental works in the following areas: TRACK-1: Theoretical and Experimental Fluid Mechanics and Heat Transfer TRACK-2: Petroleum Exploration, Petroleum Refining and Petrochemicals TRACK-3: Computational Fluid Dynamics & Heat Transfer TRACK-4: Thermal Science & Engineering TRACK-5: Energy Materials TRACK-6: Multiphase Flow TRACK-7: Nuclear Science and Engineering Please find the details of call for papers (CFP) for ESMOC 2024 inviting the abstract for plenary sessions, keynote sessions and contributed sessions. We request you to inform your group about ESMOC 2024. We hope, ESMOC will achieve another successful milestone on its journey with the contributions from you. Yours sincerely, ESMOC 2024 - 4th Energy System Modeling and Modeling Conference
