CFD modelling with ORCA

Colt has relied on Computer Fluid Dynamics to investigate ventilation designs for over 20 years. This is an extremely valuable tool to simulate airflows and heat exchange within a building, and to model how they will be affected by different design approaches. Until recently it required one of our small teams of highly skilled CFD engineers to input the data correctly and use the program, which created a bottleneck.

Our team started the ORCA project to resolve this issue, creating an easy-to-use interface that anyone designing a ventilation scheme could use. This means that they will be able to get a better understanding of the results of any design changes. The new interface also brings the benefits of this exceptional tool closer to our customers, enabling our teams to provide them with models of the proposed solution much faster and show them the simulations on site using a CFD viewer that shows the outputs with intuitive graphics.

Since its introduction ORCA has proved to be as valuable a tool as we had anticipated. Recently we are launching an upgrade, Version 2.0, which has brought about better visuals and new functionalities. It replaces ORCA’s core technology with a very reliable and stable game-engine to support the 3D graphics. Version 2.0 also extends the library so that the functionalities includes additional products, such as the popular CoolStream, sources of welding fumes, and also scenarios showing fire and smoke movements in a wide variety of buildings including car parks.
