“…Therefore, the power Pel is proportional to the electrical conductivity σ, the square of the gas velocity v, and the square of the intensity of the magnetic field B. In order to reach a competitive operability with existing electric generators, the MHD system needs to have a high conductive gas, at high temperature, high speed, compatibly with the increase of the turbulence, and an extremely intense magnetic field (5-7 tesla), coherently with the costs for the necessary superconducting magnets [27][28][29].…”

A layout of urban waste fired zero emission power plant is described in this paper. The principle of layout, which comes from similar coal-fired plants retrieved from the literature, integrates gasification with a power generation section, and implements two parallel conversion processes, one supplied by the heat of the gasifier consisting of a thermoacousticmagnetohydrodynamic (TAMHD) generator, while in the second one the syngas is treated in order to obtain almost pure hydrogen, which is fed to fuel cells. The CO2 deriving from the oxidation of Carbon base is stocked in liquid form. The novelty of the proposed layout lies in the fact that the entire conversion is performed without solid moving parts. The resulting plant avoids any type of emissions in the atmosphere, increases mechanical efficiency as compared to traditional plants, thanks to the absence of moving parts, nonetheless, resolving at its root the ever-increasing waste-related pollution problems.

High heat flux and radio blackout are well-known challenges space vehicles have been facing during re-entry into a planet’s atmosphere since the early days of space-flight. Thermal protection systems have been developed to protect spacecraft and astronauts, however, they are often heavy and some have to be replaced after each mission. High temperatures in the compressed gas in the shock wave lead to partial ionization. The dense plasma can cause radio blackout, i.e. attenuation or reflection of radio waves thus blocking data-telemetry and communication with ground stations or satellites. One approach to solve both problems is to influence the plasma with magnetohydrodynamic effects using a strong magnet. In the framework of the European project MEESST (Magnetohydrodynamic Enhanced Entry System for Space Transportation) heat flux mitigation and radio blackout mitigation is investigated by means of modelling and ground experiments in plasma wind tunnels at the Institute of Space Systems (Stuttgart, Germany) and at the Von Karman Institute for Fluid Dynamics (Brussels, Belgium) using an HTS magnet. After a short introduction to the scientific background of the MEESST project, the boundary conditions for the design of the magnet and calculations of field distributions are presented. The pancake coils of the magnet were wound with a robotic winding system. Results from a preliminary test of the conduction-cooled magnet are presented.

The renewed interest in hypersonic flights due to NASA’s Artemis program has brought fresh attention to the physical challenges of reusable thermal protection systems. The need to enhance the reliability of hypersonic and re-entry vehicles has sharply focused on the limitations of our current comprehension of thermo-chemical non-equilibrium flows and our limited predictive capabilities. This paper presents the work carried out by the University of Southampton and our consortium partners within the MEESST collaboration. This project is currently involved in both numerical and experimental research to develop magnetic shielding techniques for atmospheric re-entry vehicles. These techniques aim to offer additional approaches for mitigating both impinging heat loads and communication blackout. Herein, we present the results of multi-physics simulations conducted with the University of Southampton’s HANSA toolkit, along with comparisons, both experimental and numerical, produced by our consortium partners. These encompass simulations of multiple capsules undergoing atmospheric re-entry and simulations of ground-based experimental campaigns. We give particular attention to the effects of thermo-chemical non-equilibrium and MHD modelling. We illustrate the impacts of various mathematical models on the results obtained, with a strong emphasis on mission-critical parameters such as surface heat fluxes and electron densities. We also present conclusions regarding the implications of these results on magnetic shielding designs. Lastly, we offer an overview of current knowledge gaps in areas crucial to MEESST and lay out plans for future simulations and experiments, both within the MEESST project and beyond.
