F1-20- Osborne Reynolds’ Demonstration

The Flow Channel introduces students to the characteristics of flow in an open channel at an elementary level.

Description

The Flow Channel introduces students to the characteristics of flow in an open channel at an elementary level.

  • Demonstrating basic phenomena associated with open channel flow
  • Visualisation of flow patterns over or around an immersed object

This item is intended to reproduce the classic experiments conducted by Professor Osborne Reynolds concerning the nature of laminar and turbulent flow.

DESCRIPTION

The equipment operates in a vertical orientation. A header tank containing stilling media provides a constant head of water through a bellmouth entry to the flow visualisation pipe. Flow through this pipe is regulated using a control valve at the discharge end. The flow rate of water through the pipe can be measured using the volumetric tank (or measuring cylinder) of the Hydraulics Bench. Velocity of the water can therefore be determined to enable calculation of Reynolds’ number.

The equipment uses a similar dye injection technique to that of Reynolds’ original apparatus to enable observation of flow conditions.
