Investigation of Grooved Circular Jet Flow Experimentally and Using Computational Fluid Dynamics

Abstract

This study is the investigation of grooved circular jet ow experimentally and using computational uid dynamics (CFD). Experimental studies were conducted by using straight circular and grooved circular tubes in a multi-purpose low-range subsonic wind tunnel. Single channel hot wire anemometer was used in turbulence measurements. Numerical studies for the solution of jet ow were performed through FLUENT program (ANSYS 14.5).Jet ow proles at dierent velocities were formed by using the data generated at predetermined stations in the Re b ). These parameters were calculated with reference to jet radius and jet half width. Graphics formed by the generated non-dimensional data were compared to the previous studies.

Prediction of Inner Grooved Circular Jet Flow with Artificial Neural Networks

“…To obtain a jet flow, a secondary air generator was used, as shown in Fig. 2 [1]. An inner grooved copper tube having length of 1.2 m and inner diameter of 16 mm was used for measurement of the jet.…”

“…This study is the contunuation of the work done by Inan and Sisman, where inner grooved circular pipe flows were studied experimentally and numerically [1].…”

Prediction of Round Jet Flow with Artificial Neural Networks

“…Previously the authors have conducted experimental and numerical studies about inner grooved circular jet flow. Jet axial velocity U e , jet half width b, the Reynolds number in respect of jet half width ReD values were presented in tables and graphics [1]. The layout of the experimental setup is shown in Fig.…”

“…This study is the continuation of the work done by Inan and Sisman, where plain circular pipe flows were studied experimentally and numerically. In this study, artificial neural network (ANN) method is used to calculate the intermediate values in the previous study [1].…”

A Temperature Error Correction Method for a Thermometer Screen

“…CFD is a numerical simulation method that can model fluid flow and heat transfer in a multi-physical field [30,31]. Richardson modeled the airflow through a Gill screen using a CFD software Fluent to attain the airflow profile inside the screen.…”
