How Does Object Shape Influence Water Flow Patterns?

[ArielGenesis]

I have a physics project and i chose the topic of fluid dynamic (i don't know of it is really fluid dynamic but i think that is close enough). My level is only a high school student for information, in order to avoid any over complicating explenation.

The concept is simple:

first pour a glass of water on the florr.
Then you can see a the water spread
Wait until it stop spreading
Then the water have a certain thick ness

I some how able to have a flowing water of that thickness at a constant speed
then i put an object, like my palm for instance
the water would create a very interesting pattern.

The pattern could show a laminar flow.
I am not sure if what i thought as turbulet flow is actually a turbulent flow. coz the flow are not smooth yet stil fully transparent and no vortex has appear.

my problem is that i can't explain the pattern form in association with the shape and size of the object, if i change my palm with some thing for example.

i had taken some picture any i have trouble of posting it,
i made some attemp on analyzing the pattern, however, i can't be sure if my analysis is correct.

the pictures were at www.geocities.com/arian_m3/fluid.html

thank you. and sorry about my english

I repost this as in the last post, i posted big images which was untidy amd i had difficulty to edit them.

Fluid dynamics is the study of the motion of fluids and the forces on them. It can be used to describe the motion of water, air, and other fluids, as well as the forces acting on them. In your experiment, you are observing the effects of a flow of water around an object, such as your hand. Depending on the shape and size of the object, the water will flow around it in different ways, creating different patterns. These patterns can be used to identify different types of flows and to understand the forces that are acting on the object. For example, laminar flow is characterized by a smooth, steady flow of water, while turbulent flow is characterized by an unpredictable, chaotic flow. By changing the shape and size of the object, you can observe different patterns of flow and different forces acting on the object.
