The Impact of Mechanical Engineering Innovations on Society: Hybrit, 3D-printed Heart, ASCEND, PlantSight, and APMonitor
Mechanical engineering is a branch of engineering that deals with the design, construction, and operation of mechanical systems, devices, and machines. It plays a vital role in various industries, such as aerospace, automotive, energy, healthcare, manufacturing, and robotics. Mechanical engineers use their knowledge of physics, materials science, and mathematics to solve problems and develop new technologies that improve our lives and well-being. In this article, we will explore some of the recent innovations in mechanical engineering that have impacted our society in various domains, such as steel production, healthcare, chemical engineering design, and digital twin technology.
Hybrit: Hydrogen-based Steelmaking for Zero Carbon Emissions
The production of steel is a major contributor to global carbon dioxide emissions, accounting for about 7% of the total emissions, according to the World Steel Association. Most steel production currently relies on coal as a reducing agent to remove oxygen from iron ore and produce iron, which is then converted to steel. This process generates large amounts of carbon dioxide and other greenhouse gases, contributing to climate change and environmental pollution.
Hybrit is a Swedish joint venture between three companies: SSAB, LKAB, and Vattenfall, which aims to revolutionize the steel industry by using hydrogen instead of coal as a reducing agent in the steelmaking process. Hydrogen-based steelmaking can produce steel without any carbon dioxide emissions, as the only byproduct is water vapor. This can reduce the carbon footprint of the steel industry significantly and contribute to the global efforts to mitigate climate change.
According to Martin Lindqvist, the CEO of SSAB, "Hybrit has the potential to reduce Sweden's total carbon dioxide emissions by 10% and Finland's by 7%." The long-term goal of Hybrit is to achieve fossil-free steel production by 2045, which could be a game-changer for the steel industry and the environment.
3D-printed Heart: Personalized Medicine with Realistic Heart Replicas
The human heart is a complex and vital organ that can be affected by various diseases and conditions, such as heart failure, congenital heart defects, and arrhythmias. Treating these conditions often requires surgical interventions, such as heart valve replacements, pacemaker implantation, and heart transplants. However, choosing the best implant for each patient can be challenging, as the size, shape, and function of the heart can vary significantly among individuals.
MIT engineers have developed a novel approach to address this challenge by using soft robotics and 3D printing to create realistic heart replicas that can mimic the shape, size, and function of a patient's heart. These replicas, called "phantom hearts," can be customized to each patient's specific anatomy and pathology, allowing doctors to simulate and test different surgical scenarios before the actual procedure.
According to Ellen Roche, a former MIT postdoc who worked on the project, "The whole idea of the phantom heart is to try to replicate the patient's anatomy so that it can be used as an educational tool or for surgical simulation." The phantom hearts can also be used to test and improve cardiac implants, such as pacemakers, by assessing their compatibility and functionality in realistic conditions.
ASCEND: Open-source Software for Chemical Engineering Design
Chemical engineering is a discipline that deals with the design, optimization, and control of chemical processes and plants that transform raw materials into useful products, such as fuels, plastics, pharmaceuticals, and food. Designing and optimizing these processes and plants can be a complex and challenging task that requires a thorough understanding of the underlying physics, chemistry, and mathematics.
ASCEND is an open-source software that can help chemical engineers to create and solve complex mathematical models of physical systems, which can be used to simulate and optimize various chemical processes and reactions. ASCEND stands for "Advanced System for Chemical Engineering Numerical Data," and it was developed by a team of researchers led by Professor Michael Westerberg at the Norwegian University of Science and Technology (NTNU). The software is free and open-source, which means that it can be downloaded and used by anyone, anywhere in the world, without any licensing fees or restrictions.
ASCEND can be used to model a wide range of chemical processes and systems, including mass and energy balances, thermodynamics, fluid dynamics, and transport phenomena. The software uses a graphical user interface (GUI) that allows users to create and edit models using drag-and-drop functions and predefined templates. The software also provides a scripting language called PyASCEND, which allows users to extend and customize the software's functionality using Python.
ASCEND has been used in various research and industrial applications, such as process design and optimization, reactor engineering, separation processes, and product development. For example, ASCEND has been used to model and optimize the production of biodiesel from waste cooking oil, the design of a methane reforming reactor for hydrogen production, and the optimization of a distillation column for the separation of a mixture of solvents.
ASCEND's open-source nature has also led to the development of various add-on modules and libraries by the user community, which further extends its functionality and applicability. Some examples of these modules are the ASCEND Life Sciences library for modeling biological systems, the ASCEND-Tutorial library for learning and teaching ASCEND, and the ASCEND Process Integration (API) library for integrating ASCEND with other process simulation software.
ASCEND's open-source and collaborative nature has enabled chemical engineers and researchers from around the world to share knowledge, tools, and resources, and to contribute to the advancement of the field. ASCEND has also contributed to the democratization of chemical engineering, by providing free and accessible tools for students, educators, and researchers in developing countries and underserved communities.
ASCEND is just one example of how open-source software can empower engineers and scientists to tackle complex and pressing challenges facing our society. By providing free and collaborative tools for modeling and simulation, ASCEND can help accelerate the development of innovative and sustainable solutions for the chemical industry and beyond.
Moreover, open-source software has the potential to democratize access to critical technology and knowledge, enabling more people to participate in research and development efforts. It can also promote transparency and reproducibility, which are essential for building trust in scientific findings.
In addition to ASCEND, there are numerous other open-source tools and platforms available to engineers and scientists. For instance, OpenFOAM is a widely used software for computational fluid dynamics simulations, while R and Python are popular programming languages for data analysis and machine learning.
Furthermore, many scientific journals and conferences now encourage researchers to make their code and data openly available, which can further promote collaboration and knowledge-sharing within the scientific community.
Overall, open-source software has the potential to revolutionize how we approach scientific and engineering challenges, by enabling greater collaboration, transparency, and accessibility. As such, it is an important tool for addressing the complex and pressing problems facing our society, from climate change to healthcare.
