CFD Analysis of Hurricane Wind Forces on Mobile Homes
The effects of hurricane wind forces are particularly destructive when fragile structures, such as mobile homes are in its path. However, tenting may be used to divert the high impact wind forces away from the structure sidewalls.  Simulent Consulting Inc. was asked to determine the effectiveness of this concept.

Using state-of-the-art Computational Fluid Dynamics (CFD) codes to accurately simulate the turbulent flow fields around mobile homes, with or without tenting, Simulent proposed a series of full-scale simulations and was able to show the effects of wind speed, wind direction, tent shape, textile properties of the tent, rain drops and modified air density on tenting over mobile homes.

Development of Software Tools for Nozzle Performance Simulation

Creation of a fountain starts when an artist sketches the design on paper. Then, an engineer details the technical requirements and selects the appropriate nozzles and pumps. Sometimes, when new nozzles/configurations are being tested, the selection is installed in a workshop pool, where the artist can actually play with his/her imagination using the wheels and sliders on a control console. However, such workshop testing is labor intensive, costly, hard to adjust, and any slight change may require nozzle replacement or relocation. Further, large fountains cannot fit into the workshop.

Simulent Consulting overcame these limitations by creating a computer program to model the fountain behaviour and to simulate the water show thus giving the artist a graphical user interface to visualize his fountain creation in 3D and allowing him to easily turn the power of his imagination into reality and to make modifications to his creations at no extra costs.

Pipe coating with Solid Epoxy and Liquid Resin

Pipes, copper or otherwise, carrying water in residential, commercial and industrial settings have limited life spans and need to be replaced after a few decades. The application of a thin protective coating of a nontoxic, chemical-resistant epoxy to the interior of existing pipes, makes it possible to extend their lifetime without replacement sealing any holes and covering corroded areas. This coating method has proven to be very effective for medium sized pipes.  However for smaller pipes(1/2” to 2”) there was an issue with the coating at 90o bends and parts of the straight pipe following bends.

Simulent Consulting Inc. was asked to document the nature, characteristics and behaviour of the epoxy flow through pipes in multiple configurations when driven by air from behind and to create an automated operational and sales interface software system that would increase the efficiency and effectiveness of the application of epoxy and provide application parameters and precise application instructions to simplify sales proposal generation and increase the accuracy of the biding process.

A combination of experimental work and numerical simulation was used to understand the lining procedure as well as to find out the effect of different parameters on the lining.  The modelling was done by coupling two types of simulations. Gas Phase modelling and Particulate phase modelling.
