This paper proposes a stage flow parameter analytical model for rapid evaluation of counter-rotating compressor’s performance design optimization and its application in the transonic fan. In first part, velocity diagram method, considering influence flow-path geometry variation enhancing accuracy, is used to correlate aerodynamic between inlet guide vane (IGV), upstream rotor (R1), downstream C...

In this master thesis the flow behavior and the performance of a bow tunnel thruster at slow forward vessel motion is studied using Computational Fluid Dynamics (CFD). In this Definition Study a literature study is made, fundamental theory is explained and a roadmap for the master thesis is developed. At Royal IHC it is noticed that trailing suction hopper dredgers experience a significant decr...

This paper addresses the challenge of Solution Veri cation (SV) and accuracy assessment for computing complex Partial Di erential Equation (PDE) model. Our goal is to provide a postprocessing software infrastructure that can be connected to any existing numerical simulation software, for example, widely used commercial applications such as ADINA, Ansys, Fluent, Numeca, Star-CD etc... and provid...

This paper addresses the challenge of Solution Verification (SV) and accuracy assessment for computing complex Partial Differential Equation (PDE) model. Our goal is to provide a postprocessing package that can be attached to any existing numerical simulation package, for example, widely used commercial codes such as ADINA, Ansys, Fluent, Numeca, StarCD etc... and provide an a posteriori error ...

As the analysis tool the well-known commercial software package (FINE/Design3D) is used. As the optimization software IOSO PM (parallel algorithm of IOSO) is used. The prospect presents the results of optimizing a three-stage axial compressor. The optimization goal was to improve the compressor efficiency at two flight conditions by optimizing geometry of the 5 compressor rows (62 design parame...

The unsteady velocity and temperature fields are measured in a straight smooth and rib roughened square duct, representative of a stator cooling channel. The mainstream Reynolds number is 3 10. Single cold and hot wire probes as well as a dual hot/cold wire probe are used for this purpose. The experimental results are compared to the predictions from FINE, a commercial software package develope...
