Findings on Ventilation Research Reported by Investigators at National Center for Scientific Research (CNRS)

February 11, 2014

By a News Reporter-Staff News Editor at Journal of Technology -- A new study on Ventilation Research is now available. According to news reporting out of Vandoeuvre les Nancy, France, by VerticalNews editors, research stated, "A quadrature method of moments, based on the population balance approach, was chosen to model nanoparticle coagulation and transport. Such a way has been already validated using experimental results in a homogeneous closed chamber in a steady fluid."

Our news journalists obtained a quote from the research from National Center for Scientific Research (CNRS), "In order to model the spatiotemporal evolution of a nano-aerosol, we propose here to couple the population balance equation (PBE) with computational fluid dynamics (CFD) considering a uniform pipe flow. A source term describing coagulation is added in convection-diffusion equations. This method is evaluated by considering convection and coagulation of an aerosol in the pipe. Computational performances are then assessed by comparison with experimental results."

According to the news editors, the research concluded: "This method seems to be suitable for the future modelling of nano-aerosol dynamics in the workplace."
