- A theoretical method to solve acoustical radiation modes and acoustical radiation efficiency of complex structure by a boundary element method and acoustical radiation theory is posed in this paper.
- Fill your radiator with water, or your engine will overheat.
- The radiator is giving out a lot of heat.
- Shall I put some anti- freeze in the radiator?
- Sit by the radiator and get warm.
- It is important in ASAC system based on acoustic radiation modes to obtain adjoint coefficient of the radiation modes.
