Laser stimulated downward combustion propagation phenomenonBy Vinayak Malhotra
Abstract: Enhanced energy requirement has necessitated active research efforts to understand combustion behaviour in presence of alternative energy sources. In the last five decades, emphasis on combustion focuses on two aspects viz., improving quality of combustion and addressing the risks/hazards. With recent advancement, an aspect which is researched upon is the combustion behaviour in the presence of laser flow. Their applications pertain to propulsion, energy generation, artillery, fire safety and defence …

Perforated Forced Convection Peculiarities and ImplicationsBy Vinayak Malhotra, Shourya Mahendra Singh, Koshika Pandey, Tanooj j
Abstract: Transfer of heat through perforated forced convection within a confined passage on a flat plate is investigated for varying flow speeds. Experimentation relates to the need of comprehensive understanding of complicated heat transference requirement particularly in space propulsion domain. The optimal utilization of perforated enclosures with distinct shapes and sizes is predicted for wide-ranging applications. Systematic experimentation is carried out and effect of controlling parameters is explored. Results indicate that …

A Parametric Investigation on the Drag Effect Consideration in Re-Entry Vehicle PerformanceBy Vinayak Malhotra
Abstract: Rocket adaptation relies more on normal gravity experimentation and simplified conventional theories. The related complexities and lack of well-defined prediction system have always restricted futuristic missions. The work primarily addresses issues related to the accurate prediction of rocket dynamics and re-entry vehicles. Parametric study on the conventional equation systems was carried out with consideration of geometric and design variables. Emphasis is put on the practical cases with minimization of assumptions. …

Feasibility of Optimized Heat Source Assisted Combustion in Solid Rocket MotorsBy Vinayak Malhotra, Minal Jain
Abstract: Advances in rocket propulsion have a predominant role in space exploration developments. As an active chemical propulsion system, the efficiency of operations depends largely upon the nature of the combustion process and related energy transfer. Modern rockets are well known to epitomizes a distinct area of propulsion assisted by external thermal source(s)/rocket boosters. The presence of external heat source(s) encourages high possibility of fire risk/ hazards, which can adequately threaten …
