Entry Length Dependence on Re in Planar and Cylindrical Channels with Sudden Contractions
Introduction
PPT Slide
Experimental Comparison
Velocity Profile Development in a Pipe for Creeping Flow
Entry Length Correlations- Axial Flow Development
99% Development Entry Length vs. Re from Flat Profile
Results
Centerline Velocity (Vcl) Development in 4:1 Contraction, Re=0.0001
Deviation of Vcl from Fully Developed Downstream Flow 4:1C
Entry Length as a Function of Re 4:1
Entry Length Correlation of Contracting Geomety
Deviation of Vcl from Fully Developed Upstream Flow
4:1 C
