HEAT PROSCESSES MODELS FOR A STEAM GENERATOR
Models with concentrated parameters are used to take in engineering practice. In contrary the steady and dynamics models with distributed parameters for steam generator of water-water nuclear power unit are received here. It was shown, that applying concentrated steady models may lead to wrong constructive solution in steam generator designing. Dynamic models with concentrated parameters have low accuracy compare to dynamic models with distributed parameters, especially in case of water temperature. This result is very important because the water temperature is used as a control variable.
