Hi friends
I want to design a heater and a cooler for a stirling engine. for calculating the volume of them (number of tubes and diameter of it), What should I do?

Start by getting a copy of "Stirling Engine Design Manual, 2nd Ed." by William Martini. This is available on the net free, NASA was the agency that commissioned the book.

IIRC, Allan Organ has a book referencing regenerators that is floating about on the web in PDF format

Good luck, Murph
