hello everyone i write to you as a beginner in this software and as student in my last semester where i work on my graduation project i have seen that this software could be very helpful to me especially with the difficulty to get a blade geometry with a profile which involves cooling passages and pins and fins i'm working currently on designing a blade which has different setups of pins and fins and cooling passages and from the explanation i saw on the website it seems that this could save me time by the ability to change the number of holes of angles of cooling passages...etc i'm looking now for the shortest way to get such a blade profile where i could only import and work on like the picture attached to this topic, since i'm working on innovative mechanisms of heat transfer of turbine blades, im interested only in the part of the blade, the blade with root only because i'm going to apply different setup and meshes to obtain different results for my project could anyone help me how to start with this or does anyone have a pre defined blade model where i could use in my project all the rights will be reserved for the person who can help because i'm only looking for ready designs because i don't so much time to learn the design fully on this software to be an advanced user i hope i will hear an answer of you and that would be greatly appreciated

---------------------- Turbomachinery ---------------------- This is a META-thread, which helps you to keep track of all posts relevant to Turbomachinery. - The first post should contain links to all relevant threads. It is re-edited regularly. - I try to keep this META up to date. However, I don't always catch everything, so please post links to any threads you think should be here. I will add them to the existing ones in the first post and periodically clean all other post from this thread.

Hi together, CAESES can be used for designing a variety of turbomachinery and engine components (impellers, volutes, ducts, axial blades,...). I have attached some pictures and animations, just to give you an idea of the applications. There is also a page about the turbomachinery industry on the CAESES website. Check out the blog where turbomachinery design stories get posted on a regular basis (most of the attached pictures are taken from these blog posts). The focus of CAESES is: Fast and efficient design studies and CFD-driven shape optimization. The robust variation (manual/automated) of turbomachinery components is really the interesting part in CAESES. The geometry models are typically highly customized, i.e., company-specific know-how can be fully integrated. There is an internal scripting environment to define custom methods and processes. Complex parametric models can be wrapped into an easy-to-use interface (so that they can be readily used by non-experts of CAESES). Parametric support geometry such as segments for the flow and structural analysis can be part of the model, too. As a side note, you can optionally plug-in your CFD tool and run optimizations right away - from within the CAESES GUI. There are integrated optimization methods and some handy post-processing capabilities. Alternatively, you can use your own optimization tools and run CAESES in batch mode. There are free academic versions of the CAESES pro edition for students and PhD students, as well as trial licenses with flexible time frames. There are also special editions for small companies, start-ups and freelancers. Hope this helps, Joerg LAST UPDATE FEBRUARY 2018

How to determine a spiral volute casing (turbocharger, pump) cross sectional decrease in value? I am trying to design a volute casing. Problem is, I don't know how much its cross sectional area decreases over time. For instance starting cross sectional area (0 degrees) is 100 cm^2, what will it be when it reaches 45, 90 degrees and so on? Is there any way to calculate it? I am sure that knowing starting and finishing cross sectional areas size (btw I know them) and just connecting them isn't a correct way.

Here is a recent article about turbine wheel optimization where the blades and the scallops can be optimized at the same time within a fully-automated process. Such a "complete" and variable model allows you to consider the aerodynamic performance (CFD) and the stress characteristics of each generated design. Comes with a set of nice animations.
