Is the use of "effect" in the following sentences correct grammatically and conceptually? If it is not , kindly suggest ways to make it clearer.

The tip leakage flow has a higher effect than the endwall boundary layer flow on the turbine torque at high flow coefficients because the endwall boundary layer flow affects hub section of the blade and this section of the blade has a smaller radius than the tip section for producing the torque.

Is it better to use of "stronger effect"?

Explanation:

The tip leakage flow and endwall boundary layer flow reduce the turbine performance. But the effect of tip leakage flow is much higher than that of endwall boundary layer flow on the torque at high flow coefficients.

I suggest 'greater effect' because it's less dimension specific.

You're probably right, and I understand the confusion, because of course we use these adjectives in many different ways. I was trying to suggest an improvement without getting into a challenging explanation, but that's rather a lazy way out, so here goes: I'll shorten the sentence for clarity and simplicity.

Tip leakage flow has a higher effect on torque.
The effect on torque can (and certainly would) be quantified in testing. Torque would be measured and represented with numbers (newton-meters or something similar). And the numbers representing that torque (loss) would be higher (larger numbers) in one case than in another. That would be the quantitative analysis. The qualitative analysis would be to simply state that the effect is 'more' or greater from one cause than the other.

The original statement is a general statement summarizing tests, so the more general term is appropriate, in my opinion. Beyond that, I guess RobertJ and I will have to agree to disagree and the OP will have to find a higher ;-) authority to consult.
