However\, in the last\ntw o decades\, a series of surprising discoveries have uncovered a new\nkind of turbulence that does not require pumping wind or rapid pipe\nflow: Acti ve turbulence. First observed in swarming bacteria\, this\nphenomenon desc ribes the chaotic flows seen at extremely small scales\n(near zero Reynold s number or flow speeds). As more biological and\nartificial systems are s hown to exhibit active turbulence\, the\ninterest in theoretical and compu tational modelling has grown\ncommensurately. Here I will present a minima l model of active\nturbulence that reproduces flow patterns seen in kinesi n-microtubule\nsuspensions (which resemble the surface of a cell)\, and di scuss the\ntransition to turbulence in this model and the computational as pects\nthat go into this -- data analysis and visualisation\, and CUDA\nim plementation of an implicit PDE solving scheme for accurate\nlong-time sim ulations. The physics and maths will be largely fun and\ninformal\, with a bit more detail on the computing side.\n\nBiography: Malcolm is a lecture r in the Department of Mathematics and\nApplied Mathematics at UCT. He com pleted his PhD in computational and\ntheoretical nonlinear dynamics applie d to polyatomic systems at UCT in\n2020. He went on to do a joint postdoc with the Maths Department and\nthe Scientific Computing Research Unit at U CT in dynamics of chemical\nreactions\, followed by two years at the Max P lanck Institute for the\nPhysics of Complex Systems and the Center for Sys tems Biology Dresden\,\nworking on active turbulence and the interface of nonlinear dynamics\nand biophysics.
