The field of gas dynamics, which deals with the study of compressible fluid flow, is a critical area of study in mechanical engineering. With the increasing use of computational methods for analyzing complex fluid flow problems, our students must gain hands-on experience using CFD tools for solving gas dynamics problems. The course aims to provide students with experiential learning opportunities to understand the concepts and applications of CFD in gas dynamics. As part of classroom learning, students are instructed to identify a problem related to compressible fluid flow and perform a CFD analysis for various flow conditions. This practice gave an understanding of the use of simulation software in design and analysis of compressible flow systems. Also, this experiential learning helps students to enrich their knowledge in the subject. At the end students were instructed to submit a report of the study conducted as part of the learning process.

Lego kits and Adams software can be used as tools to enhance the understanding of the kinematics of machines in several ways. Firstly, Lego kits provide hands-on experience in building and manipulating simple machines, which can help students better understand the concepts of kinematics. By physically building and testing machines, students can gain a better understanding of how different components work together to produce motion. They can also experiment with different configurations and observe the resulting motion, helping to reinforce their understanding of the principles of kinematics. Secondly, Adams software is a powerful tool for simulating the behavior of mechanical systems, including kinematic systems. Students can use Adams software to create virtual models of machines and simulate their motion, allowing them to explore different configurations and visualize the resulting motion. This can help students develop a deeper understanding of the underlying principles of kinematics. In combination, Lego kits and Adams software can be used to create a comprehensive learning experience that combines hands-on building and experimentation with virtual simulation and analysis. By using both tools together, students can develop a deeper understanding of kinematics and its applications in the design and analysis of mechanical systems.

To illustrate the integration of biology and engineering, the faculty provided a demonstration based on flow simulation in cardiovascular system.

The geometry of a patient’s blood vessel is extracted from a patient’s 3DRA data. Then it was imported to a simulation software (Ansys Fluent), and blood flow was simulated for different physiological conditions. Different hemodynamic parameters (WSS and OSI) were calculated and visualized in the post processing stage. This demonstration provided students with a real-life example of how engineering tools can be used to analyze biological systems. This approach helped students gain a realistic understanding of how biological concepts and engineering principles can be integrated in real-world applications.

One of the key performance indicators of the health status of a country is its Disaster health management. Medical health camps are of high importance to help combat health inequity. Many rural communities use medical camps to meet their health needs and receive free professional care from healthcare practitioners. Medical camps are an increasingly popular method of delivering health care to those who have difficulty accessing it. During August 2022, Kerala was affected by heavy floods. The Kuttanad area was the most affected part of the state because this region has the lowest altitude in India and is one of the few places in the world where farming is carried around 1.2 to 3.0 m (4 to 10 ft) below sea level. This area is usually prone to flood, but this time it was heavily affected. Many medical camps were organized for communities which were cut from the outside world by rising waters. The study discusses the role and impact of such medical camps in the flood-affected areas. The data was collected from seven medical camps and from 881 responders. Data was collected through informal and formal interviews and participatory observation. Researchers were shadowing different specialists, and had the opportunity through participatory observation, to see the interactions between doctors and patients. A debriefing after the consultation allowed to receive a more in-depth understanding from the doctors about each of their patients. Findings show that surprisingly 70% of the patients were women. Most patients experienced skin diseases and other symptoms related to living in a very humid environment. Children experienced the common cold, fever, diarrhea, and hematological disorders, which was expected. However, more surprisingly, many people also came with diseases totally unrelated to the flood such as rheumatic disorders, and many long-term diseases like diabetes, hypertension, heart disease, and asthma. Observations also allowed to notice the behaviour of the patients. Many of them came to the medical camp just for observing and they were confused on whether to attend it or not. Many patients were doubtful because the camp was conducted for free. It indicates that more communication and work at ground level is needed before medical camps are set up, in order to make it more efficient and to reach more people in need. Since the study is participatory in nature and during the disaster, there were challenges in maintaining the study design.
