Computational Fluid Dynamic Analysis of Advanced Circulator Water Jet

Introduction

This report documents the computational fluid dynamics (CFD) analysis done on an advanced Circulator water jet at U.S. standard temperature and pressure (STP). 

Objective

This report will determine the effectiveness difference between a standard water return and the advanced Circulator water jet invented by Advanced Space-age Systems & Engineering Technologies - ASSET. In conclusion, we want to show the tremendous cost savings that would be gained by the amazing coverage of the advanced Circulator water jet. 

Report Format

This report will present in-depth analysis plots and details as described in the objective.

Analysis Approach

This section lists the analysis approach taken. A math simulation of a water-filled pool with one water return was modeled. The analysis approach is to first calculate the effectiveness of a standard pool water return by measuring the amount of pool wall surface it can effectively wet. We will then compare this value to the calculated pool wall area that the advanced Circulator water jet can wet.

The standard pool water return was assumed to be pointed down towards the bottom of the pool. In this way, gravity effects are minimized. Then an iso-surface plot of the water velocity equal to 0.2 m/s was generated. It was felt that water velocity below this value would not result in effective wetting of the pool wall.

Using standard CAD tools, the wall area wetted by the standard pool return is now calculated. The length and width of the wetted wall area are shown in figures 1 and 2. A measured length of 93.8" by a width of 25.9" gives us 8.44 square feet of wetted area for a standard pool return if we assume a triangle dispersion pattern for the water.

The advanced Circulator water jet will inscribe an arc with a radius of 93.8 inches. If we consider a reduced area of a circle to account for the half of the circle where the advanced Circulator water jet is point up, we can conservatively calculate the wetted area for the advanced Circulator water jet as:

Wetted area (Scrubbed Area) = π r2/1.5 = π 93.82/(1.5 X 144) = 128 square feet. 

Analysis Conclusions

By taking the ratio of the two areas we can calculate the effectiveness difference between the standard water return and the advanced Circulator water jet.

Ratio: Advanced Circulator water jet (Surface Area) / Standard Pool Return (Surface Area) = 128 / 8.44 = 15.17

The advanced Circulator water jet is 1500 % more effective than a standard pool water return in terms of pool wall area wetted by the jet.

This report documents the computational fluid dynamics (CFD) analysis done on an advanced Circulator water jet at U.S. standard temperature and pressure (STP). It also determined the difference in effectiveness between a standard water return and the advanced Circulator water jet invented by Advanced Space-age Systems & Engineering Technologies - ASSET, as being 1500% more effective than a standard pool water return.
