Main Question or Discussion Point

Does anyone know about the parameters that affect the design of fan? For example, is there an optimum number of blades, or optimum curvature and shape for the blade? I suppose this has to do with fluid mechanics (which I know nuts)? Which particular equations am I looking for? Is there any book I could refer to? Thanks.

Well, you're asking some relatively broad questions. There are no easy answers. There are some folks in my company that get paid a lot of money to do the very thing that you are asking. For example, the solidity of a fan (the ratio of the number of blades vs. open area) is a tradeoff in what you need the fan to do.

There are basics that one should know when talking about fans. Here is a pretty good link on industrial fans for some reading:

For more in depth design and engineering data, you'll need to start looking at topics such as:
