  "textContent": "The present invention relates to a turbine (100), in particular a gas turbine. The turbine (100) comprises a first inner wall (101),a second inner wall (102), an inner casing (103) and a shield element (104). The first inner wall (101) and the second inner wall (102) are mounted to the inner casing (103). The first inner wall (101) and the second inner wall (102) are arranged such that an inner volume (Vi), through which a working fluid (110) of the turbine (100) is flowable, is separated from an outer volume (Vo), through which a cooling fluid (109) is flowable. The first inner wall (101), the second inner wall (102) and the inner casing (103) are arranged with respect to each other such that a cavity (105) is formed in the outer volume (Vo). The shield element (104) is arranged inside the cavity (105) such that the shield element (104) separates the cavity (105) in an inner region (107) and an outer region (106) which is formed in a radially outer position in comparison to the inner region (107). A gap (108) is formed between the first inner wall (101) and the second inner wall (102), through which gap (108) the working fluid (110) is flowable between the inner volume (Vi) and the inner region (107). The shield element (104) is arranged in the cavity (105) such that a fluid inlet is formed, through which the cooling fluid (109) is injectable from the outer region (106) to the inner region (107) for generating a predefined recirculation of the working fluid (110) and the cooling fluid (109) inside the inner region (107).",
