    • Condensational and Collisional Growth of Cloud Droplets in a Turbulent Environment 

      Li, Xiang-Yu; Brandenburg, Axel; Svensson, Gunilla; Haugen, Nils Erland L; Mehlig, Bernhard; Rogachevskii, Igor (Peer reviewed; Journal article, 2020)
      We investigate the effect of turbulence on the combined condensational and collisional growth of cloud droplets by means of high-resolution direct numerical simulations of turbulence and a superparticle approximation for ...

    • Effect of Turbulence on Collisional Growth of Cloud Droplets 

      Li, Xiangyu; Brandenburg, Axel; Svensson, Gunilla; Haugen, Nils Erland L; Mehlig, Bernhard; Rogachevskii, Igor (Journal article; Peer reviewed, 2018)
      Weinvestigate the effect of turbulence on the collisional growth of micrometer-sized droplets through highresolution numerical simulations with well-resolved Kolmogorov scales, assuming a collision and coalescence efficiency ...

    • Mechanism of unconfined dust explosions: Turbulent clustering and radiation-induced ignition 

      Liberman, Michael A.; Kleeorin, Nathan; Rogachevskii, Igor; Haugen, Nils Erland L (Journal article; Peer reviewed, 2017)
      It is known that unconfined dust explosions typically start off with a relatively weak primary flame followed by a severe secondary explosion. We show that clustering of dust particles in a temperature stratified turbulent ...

    • Multipoint radiation induced ignition of dust explosions: turbulent clustering of particles and increased transparency 

      Liberman, Michael A.; Kleeorin, Nathan; Rogachevskii, Igor; Haugen, Nils Erland L (Journal article; Peer reviewed, 2018)
      Understanding the causes and mechanisms of large explosions, especially dust explosions, is essential for minimising devastating hazards in many industrial processes. It is known that unconfined dust explosions begin as ...

    • Turbophoresis in forced inhomogeneous turbulence 

      Mitra, Dhrubaditya; Haugen, Nils Erland L; Rogachevskii, Igor (Journal article; Peer reviewed, 2018)
      We show, by direct numerical simulations, that heavy inertial particles (characterized by Stokes number St) in inhomogeneously forced statistically stationary isothermal turbulent flows cluster at the minima of mean-square ...
