Inertial and gravity wave transmissions near radiative-convective boundaries

期刊: JOURNAL OF FLUID MECHANICS, 2021; 916 ()

In this paper, we study inertial and gravity wave transmissions near radiative-convective boundaries on the f-plane. Two configurations have been cons......

Method of curved-shock characteristics with application to inverse design of supersonic flowfields

期刊: JOURNAL OF FLUID MECHANICS, 2021; 920 ()

This paper describes the development of a method of curved-shock characteristics based on curved shock theory. The proposed method is applied to super......

On the effect of velvet structures on trailing edge noise: experimental investigation and theoretical analysis

期刊: JOURNAL OF FLUID MECHANICS, 2021; 919 ()

This study is inspired by the velvety structures on an owl's upper wing surface. Anechoic wind tunnel experiments were conducted to study the effect o......

Inside rod induced horizontal capillary emptying

期刊: JOURNAL OF FLUID MECHANICS, 2021; 924 ()

The removal of a liquid blockage from a tube is of importance in many processes. If the Bond number (which measures the relative size of the gravitati......

Electric-field-controlled diffusion of anisotropic particles: theory and experiment

期刊: JOURNAL OF FLUID MECHANICS, 2021; 924 ()

We report on a theoretical and experimental study on the anisotropic diffusion of isolated prolate spheroidal particles in the presence of an aligning......

A numerical study of a bubble pair rising side by side in external magnetic fields

期刊: JOURNAL OF FLUID MECHANICS, 2021; 926 ()

The motion of a pair of bubbles rising side by side under the influence of external magnetic fields is numerically examined. Through solving the fully......

An insulating plate drifting over a thermally convecting fluid: the effect of plate size on plate motion, coupling modes and flow structure

期刊: JOURNAL OF FLUID MECHANICS, 2021; 916 ()

As a simplified model to study continental drift over the convective mantle, a thermally insulating plate is introduced to float freely over a bottom-......

Lagrangian dynamics and heat transfer in porous-media convection

期刊: JOURNAL OF FLUID MECHANICS, 2021; 917 ()

We report a numerical study of Rayleigh-Benard convection through random porous media using pore-scale modelling, focusing on the Lagrangian dynamics ......

Numerical investigation of minimum drag profiles in laminar flow using deep learning surrogates

期刊: JOURNAL OF FLUID MECHANICS, 2021; 919 ()

Efficiently predicting the flow field and load in aerodynamic shape optimisation remains a highly challenging and relevant task. Deep learning methods......

Flexural-gravity waves in ice channel with a lead
