What may lead to a large value of k on the wall in a channel flow?

I have simulated a 2d channel flow by the LaunderSharmaKE model. As it is one kind of low Re flow, so I choose the pisoFoam solver for it.Taking consideration of that there has tempreture exchange between the flow(300k) and the wall(310k), so I modify the pisoFoam solver and change it as my_pisoFoam with tempreture solverd in it.
By using my_pisoFoam solver I got the solution of the channel flow, however, I don't know why the k value is so high on the wall, and I have given a zero value for U(velocity) on the wall.
Does the temperature exchange lead to this or something else?
Any reply will be appreciable. Thanks~
