A numerical and experimental study of steam condenser working with modified rankine cycle

Abstract EN

A Numerical and experimental study of thermal and heat transfer processes in a steam condenser operating in steam power plant with steam engine was developed to build analytical model using to predict thermal profile of condenser.

Iterative technique between Engineering Equations Solver (EES) and Matlab programming was developed to find water properties.

The exit water temperature, steam flow rate, geometric dimension (diameter and tube length), convection heat transfer coefficient of water and condenser efficiency were computed using the analytic model.

Experimental results for a range of water flow rate (0.0153 to 0.0121 kg / s) with constant inlet water temperature of 25 oC were used to validate the analytical model.

Compared with a validated model, the standard deviations of analytical model are less than 4 %, and all errors fall into ±6 %.

Analytical model can be used to show the relation between thermal parameters.
