The joint Windblown Sand Modeling and Mitigation Research Group at Politecnico di Torino and Optiflow puts together in a multidisciplinary team specialists from academy and industry. Competences range from civil engineering to physical mathematics to computational modeling and simulation. Our team provides a deep understanding of the underlying physical phenomena, their computational simulation and the quantitative evaluation of the efficiency of sand mitigation measures for railway applications.
Politecnico di Torino is a "Research University" acknowledged as a centre of excellence in all over the world for the qualifying research areas of Architecture and Engineering. The development of the fields of excellence, the investment on frontier subjects, and also the support to the curiosity driven research allow a virtuous mix of basis and applied research. The University aims at networking with the socio-economical context and at opening new partnerships with companies and multinationals.
Optiflow is a Computational Fluid Dynamics (CFD) French consulting company, with more than 15 years of experience in the field of Computational Wind Engineering. Optiflow consulting activities helped architects and engineers improve wind and ventilation performances on more than 100 major architectural projects worldwide. Optiflow has a strong record in Research and Development activities and cultivates technology transfer relationships with a number of public and private research institutions.
Windblown sand represents an issue for every transportation project crossing arid regions.
It can lead to dramatic dangers for railway lines, frequent service interruptions and tremendous maintenance costs.
Windblown sand can impact railway lines serviceability and safety in a number of different ways and on different time scales.
Each of them requires special attention during line design and can only be faced with proper knowledge, prediction tools and simulation models.
Politecnico di Torino and Optiflow together offer a complete set of competences and experience
to propose adequate mitigation measures for most of these challenges.
Such challenges require a mandatory solution for safety issues (Sand Ultimate Limit State, SULS). They remain open issues at the state of the art, despite large efforts have been made in recent past. Here are some of the most relevant examples.
Such challenges are related to the railway serviceability (Sand Serviceability Limit State, SSLS). They require enormous maintenance efforts along the railway lifetime. Here are some of the most relevant examples.
The joint Windblown Sand Modeling and Mitigation Research Group at Politecnico di Torino and Optiflow has developed modeling and design competences to carry on sound and complete sand mitigation studies for large railway and infrastructural projects.
The following are some of our competence areas, among the others.
Each railway line section is characterized by its typical wind conditions, surrounding ground morphology, sand covering and more. Our team has the capacity of collecting these data and summarize them in what we called “Side Actual Net Drift”.
Different strategies can be employed:
The WSMM Group has recently designed an efficient Sand Mitigation Barrier, named SMaRT (Sand Mitigation around Railway Track), whose invention has been object of an international PCT application (number PCT/IT2015/000129). The barrier is intended to protect railway infrastructures from medium sized sand drifts. For more informations about the barrier and the possible exploitation of the patent please download our SMaRT Barrier brouchure or contact the Research Support and Technology Transfer Department at Politecnico di Torino (firstname.lastname@example.org).
An original model of transport, erosion and deposition of windblown sand has been developed by our team. It can be combined to wind simulations (CFD) to the aim of predicting the SMM efficiency.
WSMM will present its SMaRT Barrier invention to industrial stakeholders at the event organized by Politecnico di Torino.
WSMM is invited speaker at the largest railway conference in the MENA Region. WSMM will give a keynote lecture and hold a 1 day workshop.
WSMM will give a Seminar presentation on Sand Mitigation at the Italian Showcase for railway technology, products and systems.
