On Thursday March 19, 2020 at 3pm, OptiFluides will be hosting a webinar on the theme of atmospheric dispersion, in partnership with CADFEM France. The presentation will be based on a case study: the optimization of a double sensor network. For all accident scenarios leading to a chemical leak into the atmosphere, and regardless of wind direction, the toxic cloud generated must be detected by at least two sensors. This doubling of the network is essential to secure the site. However, as sensors are costly to purchase and maintain, it is also necessary to minimize their total number.
Choosing and modeling accidental release scenarios
This webinar highlights the various key stages of the simulations: choice of scenarios and model domain, choice of boundary conditions and atmospheric profiles according to meteorological conditions, choice of numerical models, etc. At the end of this first part, we can determine where the toxic cloud will be for each scenario and for each wind direction considered. In all, we are studying over 350 combinations of scenarios and wind directions.
Sensor network optimization
Calculations are performed using ANSYS/Fluent software. These results are used to optimize the sensor network. This optimization stage is essential in order to minimize the number of sensors while guaranteeing the network’s smooth operation. From an initial total of around 1,200 sensors, the network finally installed comprises only around 60. We’ll be presenting the optimization methods used.
We look forward to seeing you on Thursday March 19 at 3 p.m. to find out more.
