151-0110-00L | Compressible Flows | W | 4 credits | 2V + 1U | J.‑P. Kunsch | |

Abstract | Topics: unsteady one-dimensional subsonic and supersonic flows, acoustics, sound propagation, supersonic flows with shocks and Prandtl-Meyer expansions, flow around slender bodies, shock tubes, reaction fronts (deflagration and detonation). Mathematical tools: method of characteristics and selected numerical methods. | |||||

Objective | Illustration of compressible flow phenomena and introduction to the corresponding mathematical description methods. | |||||

Content | The interaction of compressibility and inertia is responsible for wave generation in a fluid. The compressibility plays an important role for example in unsteady phenomena, such as oscillations in gas pipelines or exhaust pipes. Compressibility effects are also important in steady subsonic flows with high Mach numbers (M>0.3) and in supersonic flows (e.g. aeronautics, turbomachinery). The first part of the lecture deals with wave propagation phenomena in one-dimensional subsonic and supersonic flows. The discussion includes waves with small amplitudes in an acoustic approximation and waves with large amplitudes with possible shock formation. The second part deals with plane, steady supersonic flows. Slender bodies in a parallel flow are considered as small perturbations of the flow and can be treated by means of acoustic methods. The description of the two-dimensional supersonic flow around bodies with arbitrary shapes includes oblique shocks and Prandtl-Meyer expansions etc.. Various boundary conditions, which are imposed for example by walls or free-jet boundaries, and interactions, reflections etc. are taken into account. | |||||

At the end of the course, they will be able to propose design improvements and protection/mitigation strategies to reduce risks and vulnerabilities of these systems. | |||||

Content | Modern technical systems and critical infrastructures are complex, highly integrated and interdependent. Examples of these are highly integrated energy supply, energy supply with high penetrations of renewable energy sources, communication, transport, and other physically networked critical infrastructures that provide vital social services.

Abstract | Carbon-based resources (coal, oil, gas): origin, production, processing, resource economics. Climate change: science, policies. CCS systems: CO2 capture in power/industrial plants, CO2 transport and storage. Besides technical details, economical, legal and societal aspects are considered (e.g. electricity markets, barriers to deployment). | |||||

Objective | The goal of the lecture is to introduce carbon dioxide capture and storage (CCS) systems, the technical solutions developed so far and the current research questions. This is done in the context of the origin, production, processing and economics of carbon-based resources, and of climate change issues. After this course, students are familiar with important technical and non-technical issues related to use of carbon resources, climate change, and CCS as a transitional mitigation measure. The class will be structured in 2 hours of lecture and one hour of exercises/discussion. At the end of the semester a group project is planned. | |||||

Content | Both the Swiss and the European energy system face a number of significant challenges over the coming decades. The major concerns are the security and economy of energy supply and the reduction of greenhouse gas emissions. Fossil fuels will continue to satisfy the largest part of the energy demand in the medium term for Europe, and they could become part of the Swiss energy portfolio due to the planned phase out of nuclear power. Carbon capture and storage is considered an important option for the decarbonization of the power sector and it is the only way to reduce emissions in CO2 intensive industrial plants (e.g. cement- and steel production). Building on the previously offered class "Carbon Dioxide Capture and Storage (CCS)", we have added two specific topics: 1) the industry of carbon-based resources, i.e. what is upstream of the CCS value chain, and 2) the science of climate change, i.e. why and how CO2 emissions are a problem. The course is devided into four parts: I) The first part will be dedicated to the origin, production, and processing of conventional as well as of unconventional carbon-based resources. II) The second part will comprise two lectures from experts in the field of climate change sciences and resource economics. III) The third part will explain the technical details of CO2 capture (current and future options) as well as of CO2 storage and utilization options, taking again also economical, legal, and sociatel aspects into consideration. IV) The fourth part will comprise two lectures from industry experts, one with focus on electricity markets, the other on the experiences made with CCS technologies in the industry. Throughout the class, time will be allocated to work on a number of tasks related to the theory, individually, in groups, or in plenum. Moreover, the students will apply the theoretical knowledge acquired during the course in a case study covering all the topics. | |||||
