✦ Synopsis

Two numerical procedures are proposed for surface condenser analysis. In the ®rst method a two-noded element is used with a variable heat transfer coecient for each element. This method is suitable for performance analysis under various operating conditions. A four-noded element is also proposed for studying the axial heat conduction eect in tubes. In the second method, shell side ¯ow and heat transfer are simulated in order to study the ¯ow distribution and pressure drop characteristics. The governing equations are solved in primitive variable form. The ®nite element method with a Eulerian velocity correction algorithm is used. These two procedures are applied to two dierent types of surface condensers and the results are found to be in good agreement with experimental data.

We present a numerical algorithm for the determination of muscle response by the ÿnite element method. Hill's three-element model is used as a basis for our analysis. The model consists of one linear elastic element, coupled in parallel with one non-linear elastic element, and one non-linear contrac
