Roughness effects in turbulent forced convection [PDF]
Journal of Fluid Mechanics, 2018 We conducted direct numerical simulations of turbulent flow over three-dimensional sinusoidal roughness in a channel. A passive scalar is present in the flow with Prandtl number $Pr=0.7$, to study heat transfer by forced convection over this rough surface.

Development of convection along the SPCZ within a Madden-Julian oscillation [PDF]
, 1996 A subtropical Rossby wave propagation mechanism is proposed to account for the poleward and eastward progression of intraseasonal convective anomalies along the South Pacific Convergence Zone (SPCZ) that is observed in a significant proportion of Madden ...
