[TRNSYS-users] type 536

[David BRADLEY]

Mlle Anis,
   It is not possible to directly change the tube diameter. The tube 
diameter has an impact on the intercept efficiency, the first and second 
order loss coefficients and on the concentration ratio. You may be able 
to calculate these values based on some theoretical knowledge of the 
collector that you are trying to model by using equations that are 
presented in a text book such as "Solar Engineering of Thermal Processes"
Kind regards,
  David
