Flow Characteristics at Asymmetric Sudden Contraction
نویسنده
چکیده
In this paper, the flow characteristics due to asymmetric sudden contraction is discussed based on experimental investigation when the flow through the contracted section passed from subcritical to critical flow. The experiments are conducted on a 30 cm wide, 45 cm deep and 10.5 m long laboratory flume. Different contraction ratios are considered. Different lengths of the contracted section are tested. Each particular model is tested under the same flow conditions to make the comparisons clear, consistent and logical. Flow characteristics such as discharge coefficient, heading up and energy loss are dealt in. The effects of the flow and contraction parameters on the flow characteristics are presented and discussed. Smaller contraction ratios produce smaller discharge coefficient and causes larger energy loss when compared to bigger contraction ratios.

متن کاملLaminar flow of a viscoelastic shear-thinning liquid through a plane sudden expansion preceded by a gradual contraction
Experimental observations are reported for the laminar flow of a viscoelastic liquid through a symmetrical plane sudden expansion preceded by a gradual contraction from a square duct. As is well known, for Newtonian fluid flow above a critical Reynolds number the flowfield downstream of an expansion becomes asymmetric. For the viscoelastic liquid investigated here the asymmetry is greatly reduc...

Pressure drop through sudden contraction in small circular pipes have been numerically investigated, using air and water as the working fluids at room temperature and near atmospheric pressure. Two-phase computational fluid dynamics (CFD) calculations, using Eulerian– Eulerian model with the air phase being compressible, are employed to calculate the pressure drop across sudden contraction.

متن کاملPhysical Modelling of Self-Aeration in a Cavitating Sudden PIPE Expansion Flow
Sudden pipe expansions have been known as efficient hydraulic energy dissipaters for a long time. The complex phenomenon of flow separation and velocity discontinuity at the interface of incoming jet and the recirculation flow, results in intensive shear and tensile rupture of the fluid and the associated destructive phenomenon of cavitation. This paper focuses on aeration in sudden pipe expans...
متن کاملIdentifying and Analyzing Stop and Go Traffic based on Asymmetric Theory of Driving Behavior in Acceleration and Deceleration
Stop and go traffic that leads to oscillate traffic flow frequently is observed on congestion flow. Unexpected reasons such as lane – changing maneuvers, lower speeds of leader vehicle and moving bottleneck cause stop and go traffic and amplifying delay and environment impacts. Stop and go traffic exactly can’t be modeled by traffic models, and also car following models based on kinematic flow ...
