SUMMARY:High speed rail tunnel aerodynamics
DESCRIPTION:Overview\nThe webinar will focus on the aerodynamic phenomena and effects associated with the high-speed passage of a train through a tunnel. We will begin by describing the pressure waves generated as a high-speed train enters a tunnel\, passes through changes in tunnel geometry\, crosses another train and exits the tunnel. Their generation\, propagation\, reflection\, and transmission will be discussed. Airflow patterns induced inside the tunnel\, influenced by blockage ratio\, tunnel geometry and train speed\, will also be presented. \nIn the second part\, we will examine the impact of these pressure waves on passenger tympanic comfort and safety\, both on the platforms of underground stations and on board high-speed trains. Their effects on tunnel equipment\, such as ventilation systems and platform screen doors\, as well as on the trains themselves\, will also be addressed. Finally\, we will discuss aerodynamic drag and the factors that help reduce it\, including the construction of pressure relief shafts or the creation of a partial air vacuum. \nThis will lead us to conclude with a brief exploration of the hyperloop concept. The presentation will be supported by experimental results and numerical simulations based on real world case studies. \nLearning outcomes\nIn this event\, you will: \n\nhave an appreciation of the aerodynamic challenges experienced in a high-speed rail tunnel environment and what measures should be taken during the design and construction of such systems\nobtain a good overview of different systems that are affected and will give the audience a general understanding of the problem.\n\nProgram\n\n5.30 pm AEDT: Presentation begins\n6.30 pm AEDT: Presentation ends\n\nAbout the speakers\n\n\n\nMichele Mossi\nPresident\, CEO and Founder\, GESTE\n\nMichele Mossi (born 1970) is a physicist and engineer who graduated from the Swiss Federal Institute of Technology in Lausanne (EPFL)\, where he also earned a PhD in aerodynamics.

SUMMARY:Digital engineering on the North East Link
DESCRIPTION:Event overview:\nDigital engineering is transforming how complex infrastructure projects are designed\, delivered\, and operated. The North East Link project in Melbourne\, Victoria\, presented unique challenges in the tunnel environment\, requiring innovative approaches to modelling\, design integration\, and lifecycle management. \nIn this session\, the speaker will detail the digital engineering requirements for the North East Link and demonstrate how Delve Underground applied computational design and digital engineering practices to overcome these challenges. The presentation will highlight practical outputs from digital engineering and show how they are being leveraged for asset operation and maintenance\, illustrating the value of digital processes throughout the project lifecycle. \nLearning outcomes:\n\nUnderstand the digital engineering requirements and challenges faced on the North East Link project.\nExplore practical approaches using computational design to overcome complex tunnel engineering issues.\n\nPresenters:\n \nElnaz Saminfar \nAssociate Digital Engineer at Delve Underground \nElnaz is an Associate Digital Engineer at Delve Underground\, bringing over 13 years of experience in digital engineering and computational design.

SUMMARY:Choosing the right VSD for tunnel ventilation application
DESCRIPTION:Overview\nIn recent years\, several tunnel projects have faced serious setbacks due to catastrophic motor failures. These failures are caused by high peak voltages\, a result of using Active Front End (AFE) VSDs combined with long motor cable lengths\, extending to 500 meters. This session examines the underlying electrical phenomena contributing to these issues and why conventional mitigation methods\, such as standard filters\, are often insufficient. \nParticipants will gain practical insight into proven engineering solutions that deliver near-sinusoidal voltage at the motor terminals\, reducing stress on insulation and extending asset life. Drawing on real-world case studies and field testing\, the session highlights key design considerations\, specification pitfalls\, and lessons learned to support more reliable tunnel ventilation system performance. \nLearning outcomes\nIn this event\, attendees will be able to: \n\nidentify the root causes of high peak voltages in AFE VSD tunnel applications\nevaluate why conventional filtering methods may not adequately protect motors apply practical design and specification strategies to prevent premature motor failure\nselect VSD and mitigation solutions that improve reliability and extend asset life\n\nProgram\nIn-person: \n\n5.00 pm AEST: Guest arrivals and registrations\n5.30 pm AEST: Presentation begins\n6.15 pm AEST: Q/A begins\n6.30 pm AEST: Event close\n\nOnline: \n\n5.30 pm AEST: Presentation begins\n6.30 pm AEST: Presentation ends\n\nAbout the speakers\n\n\n\nJoris Feekman\nRegional Sales Manager\, Danfoss Drives\n\nJoris is Regional Sales Manager at Danfoss Drives\, with over 25 years of experience in electrical drives and industrial power conversion.
