Centrifugal compressor Definition and 11 Threads

How can I calculate the absolute velocity of air at the outlet of a centrifugal compressor if I have: Diameter of impeller RPM Slip factor I've been reading for weeks and cannot seem to find the answer to this question. For anyone who is familiar with the subject, I'm sure you know about the...

I'm having a difficult time understanding Euler's turbine equation as it relates to designing a centrifugal air compressor. I need to calculate the impeller size if I know the inlet pressure, outlet pressure, rpm, and mass flow rate. The velocity triangles and definitions have me confused...

Hello everyone, Nowadays I am planning to redesign my centrifugal compressor which I designed for a subsystem in my graduation project. It's a 3D printed and brushless motor driven centrifugal compressor and its about a hand size. However, due to its relatively small size and relatively low RPM...

I have read this in my textbook about principles of operation of centrifugal compressor: "The impeller is rotated at high speed by the turbine and air is continuously induced into the center of the impeller. Centrifugal action causes it to flow radially outwards along the vanes to the impeller...

The rectangular chamber contains inclined perforated plates through which the air passes. At the top there is a blower and at the front as well as back bottom there are openings for air inlet. How do I calculate system resistance and know if a certain blower will be able to overcome it?

Hello, I have a design for a different type of aircraft. I wanted an actual engineer to give advice before I fork over for some parts to try and make a working model. Attached are some pics. some of the pics are as if it were a full size acft. But for the model I was just going to use two turbo...

Hi, As per my observation and experience, when we use evaporative cooler to cool the inlet air to the gas turbine, the compressor discharge pressure (i.e PCD or P3) rises. As, the temp. of the inlet air drops and the mass flow increases due to the increase in density, I believe the discharge...

Hi folks, I have a question regarding centrifugal compressors when a relief valve is included in the system. Allow me to explain... There is a centrifugal compressor supplying air to an aircraft engine. As altitude varies, the compressor provides enough pressure up to altitude "X" for the...

Hi I have uploaded centrifugal compressor performance curve. I want to know how Mass Flow vs Pressure Ratio curve plotted under different efficiency since efficiency is a constant for a compressor. Please help.

Hi, i'm comparing differents types of compressor to find out which one I'm going to convert into a turbine for my rankine cycle projet. And I'm wondering : are centrifugal compressors only for big power because the smallest i can find is 50 hp (which is the smallest turbo of garrett). I'm...

I would like sources for centrifugal compressor design. Anything, such as books, e-books, journals, websites, etc. will do.
