Yep, pretty sure. Indicated negative buoyancy... Like if you place a cold object in a hot fluid, the fluid in contact will be cooled and thus sink. May want to take an absolute value if you're going on to find convection coefficient, otherwise some complex numbers may pop up (Depending on how you're calculating Nusselt number)
