What is it about?
A procedure was developed, based on ANSYS-CFX, to predict the static characteristic of a TPJB, such as load capacity, film temperature, flow rate and friction torque. A thermohydrodynamic model is presented and results, obtained with different boundary conditions, are compared.

Why is it important?
Currently, the industrial manufacturers use ad-hoc proprietary codes for the design of TPJB and the prediction of their performance. However, apart from the input parameters defined by the code developer, the user can not modify the model. On the contrary, with a general-purpose software the user can implement modifications and exploit well developed toolboxes. In particular one can adopt up-to-date turbulence models and study fluid structure interaction with specific tools.
Perspectives
The approach has great potentialities that are still to be exploited. More realistic boundary conditions can be adopted. Moreover, the use of a general purpose software eases the implementation of some features, among others, the adoption of a turbulence model and the evaluation of the elastic and thermal deformation. Note that both these aspects modify the single pad analysis but do not affect the assembly method.
