Analysis on Coolant Temperature and Velocity Fields in Rectangular Channel With Horizontally Acceleration

Coolant temperature and velocity fields of rectangular channel in a marine reactor were simulated and analyzed with computational fluid dynamic codes when the ship was moving with horizontal acceleration. Effect of the mass flow rate distribution variation by ship motion on channel inlet average velocity was taken into account. The result shows that the coolant temperature and velocity fields in the channel vary significantly when the horizontal acceleration is big, but the variation time is short.
