PROBLEM TO BE SOLVED: To provide a method of improving a turbine's thermal response during transient and steady state operating conditions. SOLUTION: A flow of cooling fluid (25) in a turbine's casing (10) is made asymmetrical relative to the horizontal and vertical symmetry planes (31, 33) of the casing (10) so that the turbine's cooling symmetry planes (30', 32') are rotated relative to the turbine's geometric symmetry planes (31, 33) and thereby heat transfer at locations (27, 29) in the casing (10) with increased mass is increased.
