Beale Number

The Beale number is a parameter that characterizes the performance of Stirling engines and is often used to estimate the power output of such engines.

The Beale number equals the power output divided by engine cycle frequency, mean gas pressure and the swept volume of the power piston.

Formula

QuantityVariable[Subscript["B", "n"], "BealeNumber"] == QuantityVariable[Subscript["W", "o"], "Power"]/(QuantityVariable["f", "Frequency"]*QuantityVariable["P", "Pressure"]*QuantityVariable["V", "Volume"])

symbol description physical quantity
Bn Beale number "BealeNumber"
f engine cycle frequency "Frequency"
P mean gas pressure "Pressure"
V swept volume of expansion space "Volume"
Wo power output "Power"
