Heat transfer characteristics of fluids is rather peculiar when the bulk fluid temperature approaches pseudocritical point. In the present paper, computational fluid dynamics (CFD) methodology has been used to predict the attainment of pseudocritical temperature of steam in a typical spiral pipe. Abrupt changes in fluid properties near pseudocritical point are captured using commercially available CFD tool Ansys Fluent. The CFD methodology is first validated with experimental results available in literature for the specific type of problems. Then attainment of pseudocritical point in a steam pipe of an industrial boiler is predicted. For a specific mass velocity and heat flux condition, the axial location is identified where bulk fluid temperature attains pseudocritical point. Density, dynamic viscosity, and thermal conductivity of steam take sudden dips when bulk fluid temperature attains a value of 382.9 °C. Isobaric specific heat of steam attains its peak at the same bulk temperature. The attainment of pseudocritical point by steam in spiral tube is captured accurately with the numerical model.
