This paper reformulates the axisymmetric form of the material point method (MPM) using generalized interpolation material point (GIMP) methods. The reformulation led to a need for new shape functions and gradients specific for axisymmetry that were not available before. The new shape functions differ most from planar shape functions near the origin where r = 0. A second purpose for this paper w...

Superhydrophobic surface for dropwise condensation is prepared using hotplate solution immersion method on copper substrate. The preprocessed bare plate immersed in a consist of 0.004-0.008 M ethanol (CH3-CH2-OH) and tetradecanoic acid (CH3(CH2)12COOH) then heating the plates at 30-50?C 1-6 hours. contact angle water droplet measured low bond axisymmetric drop shape analysis, which gives maximu...

Shapes of nearly cylindrical sections of axisymmetric phospholipid membranes are studied theoretically. Describing the shape of such sections by their deviation from a reference cylinder, the wellestablished shape equation for axisymmetric bilayer membranes is expanded in terms of this deviation, and it is then solved analytically. The phase diagram shows the resulting stationary shapes as func...

Aerodynamic shape design optimization problems, such as inverse and constrained airfoil design and axisymmetric nozzle design, are investigated by applying the simultaneous perturbation stochastic approximation (SPSA) method to objective functions that are estimated during each design iteration using a finite volume computational fluid dynamics technique for solving the compressible Navier–Stok...

We consider the equilibrium and stability of rotating axisymmetric fluid drops by appealing to a variational principle that characterizes the equilibria as stationary states of a functional containing surface energy and rotational energy contributions, augmented by a volume constraint. The linear stability of a drop is determined by solving the eigenvalue problem associated with the second vari...

Drop-on-demand printing applications involve a drop connected to fluid reservoir between which volume can be exchanged, situation that idealized as sessile with prescribed flux across the drop/reservoir boundary. Here we compute frequency spectrum for these pressure disturbances, it depends upon static contact-angle $\alpha$ (CA) and an empirical constant $\chi$ relating either (i) pinned or (i...

The past year has been one of both achievements and challenges for ADSA. was highlighted by development a new strategic plan record number pages published in the Journal Dairy Science with Impact Factor (4.034) journal. However, organization also faced two major April: resignation our executive director decision to hold annual meeting virtual format second consecutive year. During fall 2020, AD...

The so-called coffee stain effect has been intensively studied over the past decades, but most of studies are focused on sessile droplets. In this paper, we analyse origin difference between deposition suspended particles in a drop and an axisymmetric deposited fibre. First, model shape fibre its evaporative flux with some approximations to derive analytical calculations. Then, for pinned conta...
