         20 . An aerosol provision device as claimed in  claim 19 , wherein the inner surface comprises one or more longitudinal recesses, which extend towards the distal end of the heating chamber. 
     
     
         21 . An aerosol provision device as claimed in  claim 20 , wherein the longitudinally extending portion of the inner surface comprises the one or more longitudinal recesses. 
     
     
         22 . An aerosol provision device as claimed in  claim 21 , wherein the one or more third air channels comprise one or more gaps defined between the aerosol generating article and the one or more longitudinal recesses, when, in use, the aerosol generating article is inserted into the heating chamber. 
     
     
         23 - 40 . (canceled) 
     
     
         41 . An aerosol provision device comprising:
 a heating chamber having for receiving an aerosol generating article which, in use, is inserted into the heating chamber in a first longitudinal direction;   one or more air inlets arranged to direct air into the aerosol provision device in an inlet direction; and   one or more first air channels arranged to direct air from the one or more air inlets in a circumferential direction.   
     
     
         42 - 46 . (canceled) 
     
     
         47 . An aerosol provision device as claimed in  claim 41 , wherein the one or more first air channels are arranged radially outward of the heating chamber. 
     
     
         48 . An aerosol provision device as claimed in  claim 41 , wherein the one or more first air channels longitudinally overlap the heating chamber. 
     
     
         49 - 52 . (canceled)
