Thermal and hydraulic performance of a graphite block

A test rig has been assembled to investigate the thermodynamic and hydraulic performance of a cylindrical graphite block heat exchanger consisting of three graphite blocks and a steel shell. The flow pattern in the heat exchanger was triple cross-flow on the shell-side (service side) with one pass per block and a single pass on the tube-side (process side).

Modeling Thermal Liquid Systems

The Thermal Liquid library provides two sensor block types: one for Through variables (mass and energy flow rates), the other for Across variables (pressure and temperature). By using the PS-Simulink Converter block, you can specify the physical units of the sensed variable.

Rubber Hydraulic Seals, V Seals, Wiper Seals

The purpose of piston seals in hydraulic cylinders is to maintain a high level of sealing performance throughout service life. For a cylinder which is exclusively single-acting, choose the type of seal designed to provide optimum sealing for single-acting functions with the thinnest lubrication film that can pass through the contact area between the seal and the cylinder surface.
