  Heat transfer from air in pipe to outside air

  This case simulates a heat transfer by convection about
  a single heated pipe which is described by a cylinder object.

  The pipe is cooled by a air flow of which moves
  in the X direction from left to right.

  The hot heat-transport medium a included in pipe has the Thot
  temperature. The temperatures of pipe wall is TEM1.
  Nu = 4.364 for a constant heat flux from hot air to the pipe wall.

  The In-Form is used for the setting of a heating source at PIPE
  VR object as

   (SOURCE of TEM1 at PIPE is :QFlux: with WHOLOB!LINE)

  where the heat flux from hot air to cold air through a pipe wallis
  QFlux=:U:*:ArOu:*(:Thot:-TEM1)

  the heat transfer coefficient from hot air to a pipe wall is
  U=1./(ArOu/(Alfa*ArIn)+1./(CondS/Thick))

  and the heat exchange coefficient from hot air to a pipe wall is
  Alfa=Nu*CondA/(2.*RadIn)

  The Q1 contains PHOTON USE commands
