Abstract: Purpose - The results obtained from previous studies are not found to be sufficient for hydrostatic bearing design optimisation since thermodynamic effects are not considered. Therefore, this research is presented with considering parameter variations based on thermodynamic effects for more efficient optimisation of bearing parameters. Design/methodology/approach - Single and multi-criteria approaches were carried out to determine the hydrostatic journal bearing design parameters so that the total performance of the system is optimal. Findings - It is seen that firstly, the results of single criteria approaches for minimum power, bearing coefficient and minimum temperature rise in circular hydrostatic axial journal bearings are not sufficient, secondly, there is a crucial need to consider multiple criteria optimisation cases and thirdly, thermodynamic effects must be taken into account for more efficient approach to compute the optimum values of bearing design parameters. Research limitations/implications - Further research is required to develop a genetic algorithm-based optimisation for bearing design problems considering thermodynamic effects and multiple criteria approaches to compare the results of present study. Practical implications - Comparison of optimisation results of single and multi-criteria approaches are given to show temperature variation effects on bearing performance. Originality/value - Although, there are some works related to design and optimisation of hydrostatic bearings, most of them consider the single criteria optimisation and thermodynamic effects are not usually taken into account. Therefore, this research is different than others since the present approach is implemented with thermodynamic effects and also not limited to single criteria approach.
