When a contmuous cylmder IS cooled by passmg lt longltudmally through a qmet flmd (free convecfion IS not consldered) then the followmg relatlon for the local heat transfer coefficlent can be glven The group d(PΓ©,)/P&. allows for the curvature of the cylmder. the fourth dlmenslonless group accommodates for lts fimte heat capaclty It has formerly been lmposslble to obtam a genera1 solution for the local heat tmnsfer coefficlent of a movmg contmuous cylinder of fimte heat capaaty Complete solutlons for specml cases are presented, whlch mclude (1) The local heat transfer coeffiaent for a movmg contmuous flat plate (no curvature) of fimte heat capaaty (model (7)) (2) The local heat transfer coefficlent for a movmg contmuous cylinder of fimte heat capaclty m a VISCOUS, not so wel1 conductmg flmd (Pr + 00) model (4) (3) The local heat transfer coefficlent to a movmg contmuous cylinder of mfimte heat capaclty (model (6)) On baas of these complete solutlons an approxlmate solutlon for the general problem of coohng or heatmg contmuous cylinders can be constructed These theoretlcal solutlons and expenmental data wdl be compared m a followmg paper C ES Vd 24 NO 4-F
