Research Water Channel Model 2403

 

 

 

The Rolling Hills Research Corporation Model 2403 Research Water Channel is the latest addition to RHRC's Eidetics line of water tunnel research products. While retaining many of the world-class features of RHRC's larger research water tunnels, the new Model 2403 is designed specifically to be an affordable water channel for conducting fluid dynamic experiments and demonstrations.

 

The Model 2403 offers views of the test section through a downstream and two side windows, all made of tempered glass.  The Model 2403 features a variable speed motor, a turbulence reducing screen and honeycomb in the settling chamber, a 2:1 contraction ratio, and dual line return plumbing... just like RHRC's full size water tunnels, Models 1520 and 2436. The Research Water Channel is ideal for in-classroom demonstrations and student research projects.

 

The Model 2403 is well suited to studying boundary layer flows over various floor surfaces, or for studying heat transfer characteristics from heated plates.

 

Optional Speed Control

The basic Model 2403 comes as a single speed unit. An electronic speed control can be added that greatly increases the flexibility of the system. Using the electronic speed control, the speed in the test section can be varied from 0 to 5 inches per second. The only buttons that are normally used are the four on the right-hand side: Start, Stop, Up Arrow and Down Arrow. The readout displays the approximate speed in the test section, in inches per second. The speed is increased by pressing the Up Arrow button and decreased by pressing the Down Arrow button. The tunnel can be stopped at any time by simply pressing the Stop button.

 

 

Calibration

RHRC pre-calibrates each Model 2403 water tunnel before delivery to ensure that the digital display displays the speed of the water in the test section, in inches per second. The electronic controller has many additional programmable features that are described in the manufacturer's Installation and Operation Manual, which is included with the tunnel.
