where W - mass flow of fluid

A = cross section area of flow s ~ perimeter of duct L = length of duct

The pumping power P is:

fip"\A/ 2.4 p~\A/ 2tj where 7j=pump efficiency.

The heat transferred in the channel is

so that:

where T, and T2 are the temperatures of the fluid, at inlet and outlet from the duct. Therefore, substituting eqn (8.13) in eqn (8.12)

Q ttpVAT^-T^A2 or

Therefore, in a given situation with specified temperatures and (P/O) ratio:

Solar Stirling Engine Basics Explained

The solar Stirling engine is progressively becoming a viable alternative to solar panels for its higher efficiency. Stirling engines might be the best way to harvest the power provided by the sun. This is an easy-to-understand explanation of how Stirling engines work, the different types, and why they are more efficient than steam engines.
