You can have a look at the following article for some reference cases calculated with hydrodynamic lubrication theory, to compare with.

I attach also results from my thesis with herringbone pattern, calculated with the same code as in the mentioned paper.

Konstantinos Poulios thanks a lot for your reply and info..thanks a lot.

For improving the tribological performance of journal bearing, the commonly used texture profiles are square, cylindrical, and spherical. Based on a detailed research review it is proved that partial texturing performs better than full texturing. In the majority of studies, partially textured distribution is located in a convergent zone of the bearing. The mechanism of improvement in tribological performance by employing partial texturing in convergent is dependent on the type of lubricant used (gas, oil, grease, etc.).

Nilesh Hingawe wow...details and good answer...thanks a lot for your feedback and answer..really appreciated it and really help me.Thanks

The texture height should be approximately of the same order as that of minimum film thickness in order to get improved tribodynamic performance.

You have mentioned in your query that, you are getting less maximum pressure with textured bearing. That means, your texture height is very large, which are effectively behaving just like an oil reservoir, but not as an flow restricting pressure dam.

Therefore, I would suggest you to try with smaller texture heights which are approximately of the same order as that of the minimum film thickness.

You can start with the simple spherical textures (which are also very easy to fabricate in real conditions), then proceed with changing the texture shape, position and aspect ratio.
