It was found that the probability density function of curvature shows the same power-law tails independent of particle size, although the probability density function of vertical velocity depends on particle size.}, pages = {418--425}, title = {Statistics of the Lagrangian Trajectories’ Curvature in Thermal Counterflow}, volume = {208}, year = {2022} }
