In this paper a cost effective numerical model for subsonic classical flutter analysis for turbomachinery is presented. The model is based on reduced order aeroelastic modeling (ROAM) approach. The prime objective of the ROAM is to significantly reduce the computational time for flutter analysis of low pressure (LP) stage blades of power turbines at preliminary design stage. A mesh free incompressible fluid solver based on boundary element method(BEM) e.g. 3D panel method is developed. The proposed ROAM is employed to perform subsonic aeroelastic stability analysis in 3D blade cascades. The ROAM simulated results are compared against experimental and high fidelity CFD-CSD model's results. The ROAM estimated results show good agreement with experimental results and prove to be much faster in execution compared to CFD-CSD model. Therefore, this gives designers and engineers a freedom to analyze multiple design iteration in very short time on normal workstation. Thus, the ROAM has immense potential for industrial use as a cost effective and faster numerical tool for design and analysis of more efficient and safer power turbines to meet the future demand of electric energy cheaply, quickly and efficiently.

“…Computational fluid dynamics (CFD) can be used to solve a variety of ship hydrodynamics problems [3] due to its relatively accurate results and shorter computational times compared to experimental approaches. Several computational fluid dynamics (CFD) applications, such as Lifting Line Theories [4], Blade Element-Momentum Theory, Surface Panel Methods, Boundary Element Methods (BEM), and Reynolds Averaged Navier-Stokes Equation (RANSE) [5], utilise various techniques to estimate the characteristics of propellers in open water. A lot of scientests use RANSE because its flow model is so close to the physical reality of flows [6].…”

In order to analyse problems with fluid flow, computational fluid dynamics is one of the most helpful tools available. This paper presents a numerical simulation of the effect of salinity on a marine propeller of an aircraft carrier in advance of the propeller open water (POW) test. A five-bladed fixed-pitch propeller is analysed using an unstructured mesh in the flow domain (PPTC - VP1304). Solving the RANSE equations describing the flow with a streamlined solver To begin, the accuracy of the numerical model was checked by comparing the results to previously published experimental data on the propeller. The verified model was then used to investigate how salinity impacted propeller performance in open water. The effect of fluctuating salinity was investigated by adjusting the properties of the flow fluid in a computational model. Lower advance ratios are where the effect of salinity, a decrease in efficiency of up to 4%, really shows up. However, it had little to no effect at higher advance ratios.
