CFD Simulations of Flow Jetting Impact and High Erosion Region in a Production Choke and its Downstream Spool
Keprate, Arvind; Bagalkot, Nikhil; perinpasivam, Agastian (Linköping Electronic Conference Proceedings;Proceedings of the 63rd International Conference of Scandinavian Simulation Society, SIMS 2022, Chapter; Peer reviewed; Conference object; Journal article, 2022)Erosion wear, a rather well-known problem in the petroleum and transport industry. Over the years there have been many different models suggested to estimate the erosion. Each model uses unique equations and is suited for ... -
Combining Computational Fluid Dynamics and Gradient Boosting Regressor for Predicting Force Distribution on Horizontal Axis Wind Turbine
Bagalkot, Nikhil; Keprate, Arvind; Orderløkken, Rune (Vibration;Volume 4 / Issue 1, Peer reviewed; Journal article, 2021-03-14)The blades of the horizontal axis wind turbine (HAWT) are generally subjected to significant forces resulting from the flow field around the blade. These forces are the main contributor of the flow-induced vibrations that ... -
Predicting performance of in-situ microbial enhanced oil recovery process and screening of suitable microbe-nutrient combination from limited experimental data using physics informed machine learning approach
P.S., Pavan; Keprate, Arvind; Bagalkot, Nikhil; P, Sivasankar (Bioresource Technology;, Peer reviewed; Journal article, 2022)Screening of suitable microbe-nutrient combination and prediction of oil recovery at the initial stage is essential for the success of Microbial Enhanced Oil Recovery (MEOR) technique. However, experimental and physics-based ... -
Prognostics for Small Bore Piping Undergoing Fatigue Degradation
Keprate, Arvind; Bagalkot, Nikhil (IEEE International Conference on Industrial Engineering and Engineering Management;2022 IEEE International Conference on Industrial Engineering and Engineering Management (IEEM), Conference object, 2022)Prognostics of Small Bore Piping (SBP) degrading due to fatigue deals with estimating its remnant useful life (RUL). This manuscript elaborates the RUL prediction procedure for SBP. Physics-based model is utilized to ... -
Reliability analysis of 15MW horizontal axis wind turbine rotor blades using fluid-structure interaction simulation and adaptive kriging model
Keprate, Arvind; Bagalkot, Nikhil; Siddiqui, Muhammad Salman; Sen, Subhamoy (Peer reviewed; Journal article, 2023)Over the course of the last four decades, the rotor diameter of Horizontal Axis Wind Turbines (HAWTs) has undergone a substantial increase, expanding from 15 m (30 kW) to an impressive 240 m (15MW), primarily aimed at ... -
Use of digital twins for process safety management
Keprate, Arvind; Bagalkot, Nikhil (Methods in Chemical Process Safety;, Chapter; Journal article, 2022)The chapter discusses the framework for developing a Digital Twin (DT) for the process safety management (PSM) of small-bore piping (SBP) on a typical offshore platform. One of the important problems during the PSM of SBP ...
