Abstract
Natural circulation loops (NCLs) are passive cooling systems consisting of a hydraulic circuit with heaters and coolers. In most of the industrial applications, the heater and/or the cooler is integrated to a pool which is absorbing or rejecting heat. This paper analyzes how the dynamic behavior of a NCL is affected by the integration of a pool to the cooler. The study considers a system where a constant heat is transferred to the loop through the heater and rejected through the cooler to a pool with evaporation. A 1-D model was developed to calculate the steady state regime and to simulate the transients of the system. This paper shows interesting results from the comparison of the NCL with and without integration to the pool.
