Which may explain why there's no heat being added to the domain - the temperature is near enough constant.
OK, the spray is pushing mass down to the right, and as air must also refill the space it's going up on the left. This is where the 2d, 2d axi-symmetric and 3d results may differ as in 2d axi and 3d you'd probably see a spray region flowing downwards and air being entrained in behind it.
The result is numerically sensible, but physically unlikely in a real 3d system.
