Anyone know how hydrogen bonding in water can enhance "density fluctuation" ?
And in first place What is "density fluctuation" ?

Hi mohsenph69, welcome to PF!
You'll have to give more context to your question to get a better answer. The density of a liquid being not strictly uniform, at any given point in the liquid the actual density will be equal to the average density, plus or minus something. My guess is that "density fluctuation" corresponds to the scale of that "plus or minus something".
