Performance of Three-Dimensional 180°-Curved Diffuser (Dept.M)

Three-dimensional representation of curved nanowires.

Nanostructures, such as nanowires, nanotubes and nanocoils, can be described in many cases as quasi one-dimensional curved objects projecting in three-dimensional space. A parallax method to construct the correct three-dimensional geometry of such one-dimensional nanostructures is presented. A series of scanning electron microscope images was acquired at different view angles, thus providing a ...

Incompressible skewed turbulent boundary layer on an end wall of a curved two-dimensional diffuser

Numerical Studies of Flow through Annular Curved Diffuser

In the present investigation the distribution of mean velocity, static pressure and total pressure are experimentally studied on an annular curved diffuser of 37.5° angle of turn with an area ratio of 1.284 and centerline length was chosen as three times of inlet diameter. The experimental results then were numerically validated with the help of Fluent and then a series of parametric investigat...

A New Three-Dimensional Sector Element for Circular Curved Structures Analysis

In this research paper, the formulation of a new three-dimensional sector element based on the strain approach is presented for plate bending problems and linear static analysis of circular structures. The proposed element has the three essential external degrees of freedom (Ur, Vθ and W) at each of the eight corner nodes. The displaceme...

Three dimensional axisymmetric simulations of fluid instabilities in curved geometry

Numerical simulations for Rayleigh-Taylor (RT) and Richtmyer-Meshkov (RM) instabilities for three dimensional axisymmetric fluids have been successfully conducted by a front tracking method. In the first simulation, we consider single mode RT instability for an axially symmetric perturbed interface in a circular tube. We compare the computed bubble velocity with theory and laboratory experiment...
