Numerical Investigation of Fluid Flow Characteristics Around Slide Gates Using Multi-Zonal Method
One method of solving the governing equations of fluid flow about complex geometries is to use multi-zonal method. In this method the overall domain is divided into small number of simpler domains. In each zone, the flow field is solved independently of other zones. The boundary conditions for connecting zones are enforced to convey the necessary linkage. This multi – zonal procedure has been a...

متن کاملInvestigation on thermal behavior of common types of roofs in buildings using computational fluid dynamics method
In this study, the influence of type and structure of different roofing systems were investigated using computational fluid dynamic method. The considered roofing systems include beam and block types (clay brick, light weight concrete block, polystyrene) and Uboot slab which were designed for 6m and 8m span. To simulate the fluid flow and heat transfer, the computational fluid dynamic method wa...
متن کاملIrrigant flow in the root canal: experimental validation of an unsteady Computational Fluid Dynamics model using high-speed imaging.
AIM To compare the results of a Computational Fluid Dynamics (CFD) simulation of the irrigant flow within a prepared root canal, during final irrigation with a syringe and a needle, with experimental high-speed visualizations and theoretical calculations of an identical geometry and to evaluate the effect of off-centre positioning of the needle inside the root canal. METHODOLOGY A CFD model w...
متن کاملEvaluation of irrigant flow in the root canal using different needle types by an unsteady computational fluid dynamics model.
INTRODUCTION The aim of this study was to evaluate the effect of needle tip design on the irrigant flow inside a prepared root canal during final irrigation with a syringe using a validated Computational Fluid Dynamics (CFD) model. METHODS A CFD model was created to simulate the irrigant flow inside a prepared root canal. Six different types of 30-G needles, three open-ended needles and three...
