I am elated to share that I recently participated in an insightful webinar titled "Cryogenics - Science and Engineering of Very Low Temperatures," presented by Dr. K.V. Srinivasan, a distinguished Scientist from the Tata Institute of Fundamental Research, Mumbai. This enlightening session was organized by the Department of Aerospace Engineering at Sanjay Ghodawat University, Kolhapur. I am grateful for the opportunity to learn from experts in the field and am excited to apply this knowledge to my future endeavors in aeronautics. #Cryogenics #AerospaceEngineering #ContinuousLearning #Engineering #SanjayGhodawatUniversity #TIFR #Webinar #AeronauticalEngineering

Witness the fascinating smoke flow visualization over a free-to-roll delta wing model mounted in a subsonic wind tunnel at the Aerodynamics lab (Mechanical Cluster), UPES under the guidance of Dr. Dhiraj. The experimental setup was designed and developed by third-year Aerospace Engineering students as a part of their project, which was financially supported through the SHODH grant provided by the university for undergraduate research. The primary objective of this student project is to investigate the wing rock phenomenon of delta wings and develop a mechanism to mitigate it, thereby enhancing wing stability. At a critical wind speed, the delta wing model exhibits a flow-induced limit cycle roll oscillation, commonly referred to as the wing rock phenomenon. This phenomenon typically occurs in very slender delta wings (with high sweep angles) at high angles of attack (α ≥ 25°). The counter-rotating wing tip vortices, prominently featured in the video, are pivotal in inducing instability in the wing, and by manipulating these vortices, the oscillations of the wing can be controlled.

I just attended the International Conference on IC Engine, Propulsion and Combustion hosted by Graphic Era Deemed to be University, presenting the paper "Comparative Study of Different Injector Configurations in a Hypergolic Bipropellant Thruster". This paper was part of my Master's thesis at TU Delft | Aerospace Engineering, which I worked on with Dr. B.V.S. Jyoti and Prakhar Jindal under the #Greenlam project funded by #HorizonEurope. In the paper we looked at three different injectors, their effect on the combustion characteristics in a HTP-kerosene thruster simulation and challenges attributed to the numerical modelling of droplet-droplet interaction.

🎓 We congratulate our colleague Juri Munk on the successful defence of his dissertation entitled ‘Influence of the geometry on the properties of the alloy Ti-6Al-4V manufactured by laser powder bed fusion’, at the RWTH Aachen University. 🎉 As part of his doctorate, he investigated the influence of the component geometry on the material properties during Additive Manufacturing via Laser Powder Bed Fusion of Ti-6Al-4V. His presented work provides a better understanding of the mechanisms that occur during the additive manufacturing process and are responsible for inhomogeneous material properties. For the first time it has been shown how efficient FEA simulation methods that have the potential to be applicable on part-scale can be utilized to predict application-relevant material properties.
