AxSTREAM Hydro Conceptual Design Suite
1 Introduction
The AxSTREAM Hydro is a software suite for hydraulic machines multidisciplinary design, analysis and
optimization, that provides an integrated and streamlined solution for the complete flow path design process for both
radial and axial pumps and turbines, starting from initial sizing from scratch ending up 3D blade profiles at the final
phase.
Starting from preliminary design (defining basic machine performance from a few simple parameters),
AxSTREAM Hydro goes through meanline (1D) and axisymmetric (2D) analysis, profiling and 3D blade design of
the buckets, finite element analysis, finishing with export of the geometry to 3D CAD model or for CFD calculation.
AxSTREAM Hydro provides full design and analysis cycle for axial and radial hydraulic turbines in a
flexible and integrated environment. The tasks user can solve with AxSTREAM Hydro are following:
Design new machine from scratch
Analyze existing machine and its performance
Redesign, optimize and upgrade existing machines
AxTREAM Hydro supports all types of incompressible newtonian fluids, including water, oil, kerosene etc.
User can work with pre-defined default fluids or compose custom one based on known physical properties
(density, wiscosity).

2 Hydraulic Turbine Preliminary Design (Axial_TURBO_Design License)
Preliminary Design procedure is used to create machine flow path design from scratch from a set of several
boundary conditions, geometrical parameters and taking into account specified constraints.
2.1 Turbine Solution Generator
Preliminary Design Solution Generator is used to produce a number of
variants (solutions) that satisfy specified boundary conditions within
applied constraints.
The usage of inverse solver allows to generate large amount of designs in
a short time (20,000 per min).
AxSTREAM Hydro can design completely new flow paths, or use the
unified stages with similar geometry. Maximum number of stages in the
machine equals to 50.
Generated set of solution can be explored using Design Space Explorer.
2.2 Axial Turbine Design Space Explorer
Design Space Explorer allows exploring a set of solution points
generated with Solution Generator.

2.3 Post-design Flow Path Adjustment
Post-design flow path adjustment
provides user with option to adjust
separate stages using changing their
geometric parameters, pressure
distribution on the chart or entire
machine endwall contours by spline.
S1/S2 flow path adjustment option enables users to optimize separate stages:
in pitchwise direction (S1 optimization) taking profile width with regard to pitch under criteria of loss minimization
in spanwise direction (S2 optimization) taking geometrical parameters with regard to outlet capacity and losses within the constraints on reaction, hub and tip diameters etc.
The optimization is performed using multistage random search with automatic adjustment of parameter variation
intervals at each step of the search.

rotation, and mixed flow paths with axial and radial stages.
Additional elements (ducts, diffusers etc) can be specified and calculated
In addition to the existing models of energy loss and seal leakages calculations, the user can add custom ones.
Streamline solver calculates next main
parameters of the flow path:
Power
Efficiency
Mass flow rate, volume flow rate;
Kinematic, thermodynamic parameters distribution
Losses in elements
Leakages and flow balance;
Distribution of parameters spanwise;
Lean calculation;
2D analysis uses streamline curvature method.
This module performs calculation of radial
equilibrium in the gaps between airfoil rows.
