This paper aims to present the effect of loop diameter on steady state performance of the two-phase rectangular natural circulation loop (NCL). A one dimensional homogeneous equilibrium model is developed to estimate the two-phase pressure drop across each section of the loop. Thermophysical properties and state properties are considered at local pressure. Uniform heat flux is applied at both evaporator and condenser sections. Mass flux is obtained by solving loop momentum equation using iterative procedure. Results are presented for different loop diameters under same heat load, gravitational head and fluid quantity. The effect of the loop diameter on the mass flow rate is also analysed.
