Design Practice in Turbo-machinery A Wise Sequence of Creating a New Machine……. P M V Subbarao Professor Mechanical Engineering Department

Two Major Levels of Creation Develop a new Idea based on Ideal Fluid Conditions – A generalized Procedure. Modify the design details for Real Fluid Conditions.

Basic Rules for Design of An Ideal Turbo-machine Enumerate the details of source or demand. Calculate Specific speed and identify the fundamental concept of operation. X 1 (Impulse)+X 2 (Reaction)+(1-X 1 -X 2 )(centrifugal) Y 1 (Radial)+(1-Y 1 )(Axial) Design of Flow Path using Conservation of rothalpy. Design blade cascade using conservation of mass and momentum. Design of Radial Geometry using Radial Equilibrium Theory. A design of an Ideal Machine….. Real Performance will be lower ……

Basic Rules for Design of A Real Turbo-machine More customized rules along with the general rules. Customized rules are specific to application: Power consumption Vs Power Generation. Radial Vs Axial. Incompressible flow Vs Compressible. In Reality: Design analysis of A Real Machine is an Exclusive Scientific Art. Define and evaluate a series of correction factors.

A Two-Way Welfare for the Globe

Varieties of Hydro Resources Available in Nature… Each Resource is naturally fit in the classification? Any modification of the resource is required for better harvesting of resource?

The Size of A Power Project A Macro Power Project : > 100 MW. A Small Power Project : 5 MW to 25 MW. A Mini Power Project : 500 kW to 2 MW. A Micro Power Project : 50 kW to 200 kW. A Pico Power Project : < 30 kW.
