![]() Cold and hot fluid blending with minimum back-pressure.A fast-acting disc valve oscillating at 20Hz.Miniature, non-contact fluid mixing for viscous formulations.PDD has already applied it to several recent innovations, including: This integrates directly with 3D CAD modelling and its access and quick learning curve is particularly suited to fast and concurrent work in early stages. Having first used an ANSYS product, PDD also recently acquired Solidworks Flow Simulation. Our adoption of FEA soon after CAD supported our work in structural, rugged and sealed products and allowed us to be pioneers in their performance.Īlongside CAD, PDD has extensive experience in fluid technology projects developing a broad range of products for various industries around the world including pharma drug delivery, HVAC, domestic appliances and technical packaging.ĬFD has proven itself to be a powerful and effective tool in these projects. ![]() This was primarily for design, communication and manufacturing reasons – and yet paradoxically this package had emerged itself from Finite Element Analysis (FEA) modelling. The story started long-ago when PDD was one of the early adopters of 3D CAD (Computer-Aided Design) in the early 90s with SDRC. As Graham Lacy, PDD’s Technical Director observes, ‘We so often find that the engineering challenges is not the simple application of complex theory – but the complex application of simple theory’. PDD apply it somewhat differently.ĬFD is best used in cases where the system behaviour cannot be calculated using conventional calculation – not necessarily because of the complexity of the maths theory – but because of the complexity of the overall system or its geometry. It is used by many industries in their development work to analyse, optimise and verify the performance of designs before costly prototypes and physical tests. Alex Hanson discusses the benefits of using PDD’s Computational Fluid Dynamics (CFD) packages as a powerful tool for creativity and exploration throughout the design process.Ĭomputation fluid dynamics (CFD) is an engineering tool used to simulate the action of thermo-fluids in a system.
