At Fieldhouse Engineering, we have access to the latest in fluid flow simulation software. We are able to model gas, liquid and heat flow through a system or in a steady state to determine how a system will behave without the need for building a physical prototype. Our highly skilled engineers are experienced in producing a model which accurately represents the proposed system or situation, so you can see how a system behaves before it’s built.
We can also model forces, stresses, and strains in a wide variety of materials, determining the strength suitability of a design, as well as the stress distribution within the item. Get in touch today to discuss your modelling requirements or see below for examples of how our simulation packages work.
Computational Fluid Dynamics
Compressible fluid flow simulations are an efficient way of solving CFD simulations where the density changes of the fluid are significant.
Density changes of gases are typically always significant therefore they are always analysed as compressible. Liquids are normally treated as incompressible as this is a more efficient way of solving these simulations, however, when a liquid has a Mach number greater than 0.3 it has to be treated as a compressible flow as the density changes become significant.
An example of a gaseous, compressible flow around an aerofoil was setup to analyse various characteristics such as the pressure, density and velocity of the air.
A Boeing HSNLF (High Speed Natural Laminar Flow) Aerofoil was modelled and setup with an airflow of 55m/s or 200km/hr which is slightly less than the take-off speed of the aircraft.
Various plots were obtained from this simulation, the Velocity Plot is shown below.
Finite Element Analysis (FEA)
Fieldhouse Engineering can perform in-depth stress analysis simulations of any structure consisting of a wide range of materials. Multiple loads can be placed in any direction at any point including torsion and compression in order to provide a realistic and useful model for your application.
A simple example is shown below in which a three-armed stainless steel bracket holds a weight of 100 Kg from a wall.
From the analysis below it can be observed that the two upper arms are in tension and the lower in compression, however the main phenomena here is bending. The weight has deflected 0.04 mm vertically exhibiting a maximum stress on the arms of 2.1 E 7 N/m^2 . The yield stress of stainless steel is 5.0 E 8 N/m^2 therefore the safety factor for this structure is 24.
By running this type of analysis any structure can be optimised such that there are no weak points. Nor will there be added expense or extra weight from over-engineered parts.
