Boiling Heat Transfer in Copper Foam Bilayers in Positive and Inverse Gradients of Pore Density [PDF]

Journal of Applied Fluid Mechanics, 2023
Gradient metal foam is an advanced heat transfer material that decreases resistance to bubble escape and enhances the transfer of boiling heat. In this study, boiling heat transfer and bubble behavior were studied in an experimental set-up with copper ...

fNL - gNL mixing in the matter density field at higher orders [PDF]

, 2018
In this paper we examine how primordial non-Gaussianity contributes to nonlinear perturbative orders in the expansion of the density field at large scales in the matter dominated era.

Mass Purification Protocol for Drosophila melanogaster Wing Imaginal Discs: An Alternative to Dissection to Obtain Large Numbers of Disc Cells

Biology, 2022
Drosophila melanogaster imaginal discs are larval internal structures that become the external organs of the adult. They have been used to study numerous developmental processes for more than fifty years. Dissecting these imaginal discs for collection is

The effect of a density difference on shear-layer instability [PDF]

, 1972
Measurements of mass flow rate and mean density have been made in separated laminar boundary layers with large transverse density gradients. Two-dimensional shear layers were formed by exhausting a half-jet of one gas into a reservoir of another gas with

The baroclinic secondary instability of the two-dimensional shear layer [PDF]

, 2000
The focus of this study is on the numerical investigation of two-dimensional, isovolume, high Reynolds and Froude numbers, variable-density mixing layers. Lagrangian simulations, of both the temporal and the spatial models, are performed. They reveal the

Bubble density gradient with laser detection: A wake-homing scheme for supercavitating vehicles

Advances in Mechanical Engineering, 2018
The poor mobility and complex target motion estimation are the two main challenges in the anti-ship attack missions of high-speed guided missiles. In this study, a new wake-homing scheme of supercavitating vehicles is proposed using the gradient wake ...
