Rotor Radius given Tip Speed Ratio Solution

STEP 0: Pre-Calculation Summary

Formula Used

Rotor Radius = (Tip Speed Ratio*Free Stream Wind Speed)/Angular Velocity of Rotor
R = (λ*V_∞)/ω
This formula uses 4 Variables

Variables Used

Rotor Radius - (Measured in Meter) - Rotor Radius is the distance from the axis of rotation to the tip of the blade in a rotor.
Tip Speed Ratio - Tip Speed Ratio is the ratio of the speed of the tip of a wind turbine blade.
Free Stream Wind Speed - (Measured in Meter per Second) - Free Stream Wind Speed is the speed of wind that occurs naturally in the atmosphere, unaffected by any obstacles or wind turbines.
Angular Velocity of Rotor - (Measured in Radian per Second) - Angular Velocity of Rotor is the speed at which the rotor blades of a wind turbine rotate around their axis.

STEP 1: Convert Input(s) to Base Unit

Tip Speed Ratio: 2.2 --> No Conversion Required
Free Stream Wind Speed: 0.168173 Meter per Second --> 0.168173 Meter per Second No Conversion Required

What is Rotar Radius?

The Rotor Radius is the distance from the center of a wind turbine’s rotor (hub) to the tip of one of its blades. It defines the rotor's swept area, which is crucial in determining the amount of wind energy the turbine can capture. A larger rotor radius allows for a greater swept area, increasing the potential energy that can be converted into electricity.
