 at least one fluid receiving feature formed in the outer surface of the body, the at least one fluid receiving feature arranged and disposed to receive post-impingement fluid from the at least one aperture,   wherein the at least one aperture does not define any portion of the at least one fluid receiving feature.   
     
     
         9 . The device of  claim 8 , wherein the at least one fluid receiving feature further comprises a fluid directing feature. 
     
     
         10 . The device of  claim 9 , wherein the fluid directing feature directs the post-impingement fluid away from the at least one aperture. 
     
     
         11 . A turbomachine casing comprising:
 an axial flow path, the axial flow path including a first portion and a second portion axially downstream of the first portion;   a nozzle cavity fluidly coupled with the axial flow path;   a passageway fluidly connecting the axial flow path and the nozzle cavity; and   an impingement sleeve within the second portion of the axial flow path, the impingement sleeve including:
 a body having an outer surface and an inner cavity within the outer surface, wherein the inner cavity is fluidly coupled with the first portion of the axial flow path; 
 at least one aperture extending through the body, the at least one aperture positioned to direct fluid from the inner cavity through the body to the outer surface; and 
 a first lip proximate a first end of the body, the first lip extending radially outward from the outer surface and sealing the first portion of the axial flow path from the second portion of the axial flow path. 
   
     
     
         12 . The turbomachine casing of  claim 11 , wherein the body and the first lip define a circumferential space between the outer surface of the body and an inner surface of the second portion of the axial flow path. 
     
     
         13 . The turbomachine casing of  claim 12 , wherein the first lip includes a slot, and wherein the impingement sleeve further includes a seal member within the slot for fluidly sealing the circumferential space from the first portion of the axial flow path. 
     
     
         14 . The turbomachine casing of  claim 12 , wherein the at least one aperture directs flow of the fluid from the inner cavity to the circumferential space. 
     
     
         15 . The turbomachine casing of  claim 14 , wherein the first lip directs flow of the fluid in the circumferential space to the passageway fluidly coupled with the nozzle cavity. 
     
     
         16 . The turbomachine casing of  claim 14 , wherein the impingement sleeve further includes:
 a second lip proximate a second end of the body, the second lip extending radially outward from the outer surface; and   a plug coupled with the body, the plug for obstructing an end of the inner cavity, the plug positioned to redirect flow of the fluid from a first direction to a second, distinct direction.
