Se­pa­ra­te mat­he­ma­ti­cal mo­dels for de­ter­mi­ning the tem­pe­ra­tu­re distri­bu­ti­on in the ele­ments of tur­bo­ge­ne­ra­tors ha­ve be­en de­ve­lo­ped, which are descri­bed ge­omet­ri­cally by an isot­ro­pic half-spa­ce and a he­at-sen­si­ti­ve spa­ce with lo­cally con­centra­ted so­ur­ces of he­ating. For this pur­po­se, using the the­ory of ge­ne­ra­li­zed functi­ons in a con­ve­ni­ent form, we wri­te the ini­ti­al dif­fe­ren­ti­al eq­ua­ti­ons of ther­mal con­duc­ti­vity with bo­un­dary con­di­ti­ons.

The  structural  and  functional  diagrams  of  the  thermoanemometric  type  sensor  for measuring  the mono-  and biphasic  (liquid  +  gas) medium  by  the  pulsating  nature  of  the  flow  are  presented.  The  temperature  distribution  in  the  sensor environment is considered and the sensing elements are not in contact with the inner surface of the sensor body.

The method of determining the integral characteristics of the temperature field of a turbine generator rotor in the case of local overheating is proposed in relation to the study of its deflections and the level of vibration; Influence of thermophysical and geometrical parameters of rotor ТГВ-500-4 on its temperature field is investigated.
