A new variant of AUSM scheme, so-called AUSM+-pcp (AUSM+ with pressure-correction projection), has been devised including a pressure-correction projection to the AUSM+ flux splitting, which maintains the exact numerical conservativeness and works well for all Mach numbers.
Iterated pressure-correction projection schemes for the unsteady incompressible Navier-Stokes equations are developed, analyzed and exemplified, in relation to preconditioned iterative methods and the pressure-Schur complement equation.
In the PDE evolution part, the phase-field equation is numerically solved by a conservative scheme with a Lagrange multiplier, and the coupled incompressible Navier Stokes equations are solved by the incremental pressure-correction projection scheme based on the semi-staggered grid method.
Then, the single-acquisition CBV images and the dual-acquisition CBV and CBF images were reconstructed from the scatter-corrected projection data by OSEM after decay correction.
Following scatter correction, the projection data are reconstructed by ordered subset expectation maximization (OSEM) [21] including point spread function (PSF) and attenuation correction.
This is done by making corrections of projection differences of original images using the digital elevation model (DEM) data (the images obtained and those to be corrected are consistent in extent) for converting the original image into orthogonal images.
All quantities were measured in the sky plane, and no projection correction has been made (from Belov et al. 2014).
α95 Fisher (1953) 95% confidence limit, k Fisher (1953) concentration parameter Fig. 7 Equal area plot of site-mean directions before and after tilt correction (upper hemisphere projection) with α 95 confidence ellipses.
Since a standardized parallel imaging technique was used for the intraoral bitewing X-rays, no correction for the projection geometry was performed.
A modified SIMPLE algorithm is used to solve the pressure and volume fraction corrections, and a projection method is used to obtain solutions of the momentum equations.
The main difference between 3D and 2D data in transparent alloy experiments is due to a stereological correction for over-projection.
