Abstract.  In the paper the governing equations of the incompressible laminar temperature boundary layer on the rotating surface are universalised using the improved method of Loitskianskii. The influence of rotation in the treated problem is separated by developing and linearising of all universal functions on rotational parameter ?. Two different boundary conditions are concerned - adiabatic surface and constant wall temperature case. Universal solutions in one-parametric approximation are obtained by numerical integration. All calculated universal functions are presented graphically and analysed, so that the influence of rotation can be distincted.

UNIVERZALNA REŠENJA NESTIŠLJIVOG LAMINARNOG TEMPERATURSKOG GRANIČNOG SLOJA
NA ROTIRAJUĆOJ POVRŠINI U radu su jednačine nestišljivog laminarnog temperaturskog graničnog sloja univerzalizovane  korišćenjem poboljšane metode Lojcijanskog. Uticaj obrtanja u razmatranom problemu izdvojen je razvijanjem i linearizacijom svih univerzalnih funkcija po parametru obrtanja ?. Razmatrana su dva različita granična uslova - adiabatska površina i slučaj konstantne temperature zida. Univerzalna rešenja u jedno-parametarskom približenju dobijena su numeričkom integracijom. Sve sračunate univerzalne funkcije prikazane su grafički i analizirane, tako da se može uočiti uticaj obrtanja.
