Flame synthesis of functional nanostructured materials and devices: Surface growth and aggregation
TL;DR: In this article, a scaling law is derived for determining the primary particle size of nascent soot aggregates from mass-mobility measurements rather than tedious image counting, in excellent agreement with microscopic and mass-mobile measurements in a standard burner-stabilized stagnation ethylene flame.
Multi-Particle Sintering Dynamics: from Fractal-like Aggregates to Compact Structures
TL;DR: In this paper, the evolution of morphology, surface area and radii of gyration of multi-particle aggregates are elucidated for various sizes and initial fractal dimension for viscous sintering.
Journal ArticleDOI
Coagulation–Agglomeration of Fractal-like Particles: Structure and Self-Preserving Size Distribution
TL;DR: The growth and structure of particles undergoing agglomeration are investigated from the free molecular to the continuum regime by discrete element modeling (DEM) and the resulting SPSD is in excellent agreement with that obtained by DEM.
The Structure of Agglomerates consisting of Polydisperse Particles
TL;DR: Df as well as Dα and ka can be an indication for PP polydispersity in mass mobility and light scattering measurements if the dominant agglomeration mechanism is known, like diffusion-limited and/or ballistic cluster–cluster coagulation in aerosols.

Efficiency enhancement of the parabolic trough solar collector using the rotating absorber tube and nanoparticles
TL;DR: In this paper, an approximate 2D-transient model of parabolic trough collectors is proposed and a steady-laminar numerical simulation is conducted for the 3D cases, which indicates that the aluminum is the best choice among the other materials used for the absorber tube, providing about 16'k higher output temperature which is nearly 5% higher than that of the steel.

Volume of fluid (VOF) method for the dynamics of free boundaries
C.W Hirt,B. D. Nichols +1 more
TL;DR: In this paper, the concept of a fractional volume of fluid (VOF) has been used to approximate free boundaries in finite-difference numerical simulations, which is shown to be more flexible and efficient than other methods for treating complicated free boundary configurations.
