Frequently Asked Questions - Basic

The two codes can be used in many industries and applicable to all types of turbomachinery including Compressible or Incompressible flow, Radial, mixed, and axial-flow machines, Rotational or Stationary and Turbine flow or Pump flow. Further details on the applications of the TURBOdesign family of design codes can be found in the Applications section.

TURBOdesign-1 enables the control of 3D pressure fields through the loading distribution, thereby allowing the user to address flow features such as secondary flows and 3D flow separation in a direct manner. It has lead to breakthrough designs in many Turbomachinery applications, its benefits are as follows:

  • Full 3D Inverse method.
  • Complete control of 3D pressure fields through blade loading.
  • Innovative design beyond previous experience.
  • Easy to export the resulting geometry to major CFD, CAD and FEA system.
  • Valuable manpower and design time savings.
  • Easy to generate database of design know how.
  • Logical feedback of CFD results to design inputs.
  • Direct portability of design inputs from one design to another.
TURBOdesign-1 is a full 3D invicid inverse turbomachinery design method. Input the blade loading, meridional geometry, thickness, and stacking axis, and in a matter of minutes you have inversely designed your blade geometry. Designers can drastically cut design times by using their insight into the flow field to design the blade rather than using trial and error. TURBOdesign-1 can be applied to the design of all types of turbomachinery blades, compressible or incompressible, rotating or stationary, axial, mixed flow or radial. TURBOdesign-1 has no shock capturing but can be applied in the transonic flow regime.
TURBOdesign-2 is a viscous 3D transonic inverse design method. It was developed in particular for the design of high pressure ratio axial transonic fans and compressors where most of the pressure rise near the tip occurs due to the shock. The code models the effect of viscosity and can capture shock waves.

TURBOdesign-1 and TURBOdesign-2 are the main software products offered, ADT also offer Consultancy and Engineering Services.

Unlike the conventional or direct approach where the geometry is changed iteratively by using the application of CFD analysis methods and through trial and error until the optimum flow conditions are obtained. With the Inverse approach the geometry is computed for a specified optimum flow distribution, where the loading distribution is specified and then the blade geometry is computed, this approach is much quicker in generating the blade geometry. The inverse approach has been used previously using 2D methods, with the surface velocity specified, but these methods offered no control over blade thickness and it was difficult to ensure structural integrity and difficult to apply in 3D because of hub to shroud compatibility conditions. Other areas of development in the Inverse method include stating the velocity on one surface and blade thickness, but it is difficult to apply in 3D because of hub to shroud compatibility conditions. Only when the blade loading, blade distribution and blade thickness parameters were entered as an input requirement that the Inverse approach ensured a design that not only satisfied structural considerations, but could be applied in 3D and allowed the possibility to design for a fixed Euler work.
