Numerical Simulation of a Radial Difusor Airflow Considering Different Turbulence Models and Computational Parameters
In the present work are presented results from numerical simulations performed with the ANSYS-CFX code. It is studied a radial diffuser flow case, which is the main academic problem used to study the flow behavior on flat plate valves. The radial flow inside the diffuser has important behaviors such as the turbulence decay downstream and recirculation regions inside the valve flow channel due t...
متن کاملNumerical Simulation of the Airflow across Trees of a Windbreak
i Abstract In the present study, the effect of the trees in windbreaks on the leeward airflow is investigated, for the first time, employing numerical models. Different arrangements of windbreaks have been considered: (i) a single row of cypress trees, (ii) two rows of cypress trees and (iii) two rows of cypress trees with a low hedge that represent shrubs in the first row. The RANS equations h...
متن کاملNumerical simulation of airflow patterns in nose models with differently localized septal perforations.
OBJECTIVES/HYPOTHESIS The most typical complaints of patients with nasal septal perforation (SP) are nasal obstruction, crusting, and recurrent epistaxis depending on the size and site of the SP mainly due to disturbed airflow patterns. The objective of the study was to determine the influence of differently localized SPs on intranasal airflow patterns during inspiration by means of numerical s...
متن کاملInflow boundary profile prescription for numerical simulation of nasal airflow.
Knowledge of how air flows through the nasal passages relies heavily on model studies, as the complexity and relative inaccessibility of the anatomy prevents detailed in vivo measurement. Almost all models to date fail to incorporate the geometry of the external nose, instead employing a truncated inflow. Typically, flow is specified to enter the model domain either directly at the nares (nostr...
متن کاملNumerical Simulation of Airflow over Potential Telescope Sites
Numerical simulation can provide a valuable tool in evaluating the characteristics of possible sites for new telescopes. This technique can provide accurate information about topographically induced atmospheric disturbances and turbulent boundary layers occurring in the high Reynolds number airflows over such sites. Results are given here for simulations of airflow at the two Gemini 8-m telesco...
