Title of Talk: Sustainable Space Exploration: Air Intakes of Reusable Launch Vehicles

Abstract

The talk begins with the need for space exploration and the players in the game. Hybrid propulsion systems offer sustainable options for space missions. One such design is to employ a scramjet engine at a certain stage in the flight. Air intakes form a vital component of an airbreathing engine of a aerospace vehicle. We investigate the performance of a mixed-compression intake using stabilized finite element methods implemented on parallel computing platforms. In the sub-critical regime, the normal shock is pushed in the convergent part of the intake leading to the "buzz" instability and "unstart". It adversely affects the mass flow entering the engine and may lead to combustion instability, engine surge and flame out. Little buzz arises due to shear layer instabilities in the intake. Big buzz occurs due to pressure pulses from the subsonic portion of the intake. Flow control techniques such as boundary layer bleed to increase the operational boundaries of these engines are explored. Similar instabilities in intakes of high speed single-engine aircrafts are discussed.

Title of Talk: Agar and Cellulose based Dressings for Faster Blood Clotting

Abstract

Uncontrolled bleeding from traumatic events such as gunshot wounds, traffic accidents, or war casualties is still one of the primary causes of mortality worldwide. In such an emergency, fast and effective bleeding management is vital to save patient's life. To address this, we have developed an agar-based hemostatic wound cryogels with oxidized cellulose and polydopamine to rapidly arrest bleeding while promoting initial wound stabilization and healing. The cryogel were fabricated using biocompatible and biodegradable polymers offering a porous architecture to support rapid blood absorption, platelet aggregation, and localized coagulation. With a 4200% swelling degree, a quicker clotting time (within 60 s), and a 4.77 kPa compressive strength, the developed hemostatic sponges showed superabsorbent hemostatic activity. In in vitro tests, the cryogels demonstrated outstanding cytocompatibility and hemocompatibility. The developed hemostatic materials exhibited exceptional in vivo hemostatic efficacy in in vivo models attaining blood clotting times of 64 s and 35 s in rat tail amputation and liver puncture models respectively. These findings suggest that the developed hemostatic materials hold strong potential for use in emergency trauma care and battlefield applications, offering a rapid, effective, and scalable solution for hemorrhage control.
