    • Characteristics of quasistationary near-wall turbulence subjected to strong stable stratification in open-channel flows 

      Atoufi, Amir; Scott, K. Andrea; Waite, Michael L (American Physical Society, 2020-06-05)
      Characteristics of near-wall turbulence at quasistationarity under strong wall cooling are studied using direct numerical simulation of open-channel flow. It is shown that if turbulence reaches quasistationarity, then the ...
    • Jets, Vortices and Turbulence in Quasi-Geostrophic Magnetohydrodynamics 

      Tessier, Jonathan (University of Waterloo, 2022-07-28)
      In this thesis, we model the dynamics of the solar tachocline and the Earth's molten core using a shallow, rapidly rotating, and electrically conducting fluid on an f-plane. We explore the effects of a strong uniform ...
    • Prandtl number dependence of stratified turbulence 

      Legaspi, Jesse (University of Waterloo, 2019-08-15)
      Stratified turbulence is affected by buoyancy forces that suppress vertical motion, resulting in a horizontally-layered structure with quasi-two-dimensional vortices. The Prandtl number Pr quantifies the relative strengths ...
    • Scale-dependent anisotropy in forced stratified turbulence 

      Lang, Christopher J.; Waite, Michael L (American Physical Society, 2019-04)
      In stratified turbulence, buoyancy forces inhibit vertical motion and lead to anisotropy over a wide range of length scales, which is characterized by layerwise pancake vortices, thin regions of strong shear, and patches ...
    • Short-wave vortex instabilities in stratified flow 

      Bovard, Luke (University of Waterloo, 2013-12-17)
      Density stratification is one of the essential underlying physical mechanisms for atmospheric and oceanic flow. As a first step to investigating the mechanisms of stratified turbulence, linear stability plays a critical ...
    • Spectral Energy Balance in Convective Boundary Layers 

      Sandham, James (University of Waterloo, 2014-12-19)
      In his pioneering 1941 papers, Kolmogorov derived that the energy spectrum follows a universial form within a range of wavenumbers removed from both the forcing and dissipation and depending only on the wavenumber and the ...
