The invention provides a turbulent flow column, a turbine blade and a gas turbine. The turbulent flow column comprises a plurality of peripheral columns, the peripheral columns are annularly arranged at intervals and form in-column spaces in a surrounding mode, inter-column channels are formed between the adjacent peripheral columns, and the inter-column channels and the in-column spaces are communicated and used for fluid to pass through. According to the turbulent flow column, one part of fluid forms turbulent flow around the column in the circumferential direction of the peripheral columns, the other part of the fluid enters the space in the column through the channel between the columns and then is discharged through the channel between the columns, and the fluid forms turbulent flow when passing through the channel between the columns and located in the space in the column. The fluid discharged from the inter-column channels and the fluid forming the turbulent flow around the column can be impacted to be mixed, so that the turbulence degree of the fluid is improved, the better heat exchange and cooling effect is achieved, meanwhile, the situation that the turbulent flow column forms a flowing dead zone in the rear portion of the fluid flowing direction can be avoided, the heat exchange and cooling uniformity is improved, and the heat exchange and cooling efficiency is improved. In addition, the multiple peripheral columns can increase the heat exchange area of the turbulent flow columns and the fluid, and the heat exchange cooling effect and efficiency are improved.
