Heat transfer into a system is normally considered positive. The sign convention from the perspective of a wall between two reactors is unchanged, with a positive value indicating heat transfer from the left to the right.

Heat transfer into a system is normally considered positive, and the internal variables used within
Reactorshould reflect this convention.This does not change the sign convention from the perspective of a wall between two reactors is unchanged, where a positive value indicates heat transfer from the left to the right, which I think is consistent.
Changes proposed in this pull request
Reactor::m_Qdotusing the updated sign convention, and use this to setReactor::m_Qfollowing the existing conventionReactor::m_Qdotin calculations for all reactor models instead ofm_QReactor::m_QThe
Reactor::m_Qvariable is aprotectedmember of theReactorclass, with no accessor, so this can only affect user-generated classes derived fromReactor. However, fixing this is important for #1003, which does introduce a getter/setter pair for this net heat transfer, and using the normal sign convention would prevent some surprising behavior.If applicable, fill in the issue number this pull request is fixing
