Is use of "have more distance" in the following sentences correct grammatically and conceptually? Is the following sentences correct grammatically?If it is not , kindly suggest ways to make it clearer.
also, center of leakage vortex for variable thickness blade have more distance from the suction surface than constant thickness blade(approximately two times more).
Yes, though consider "a greater distance" in place of "more distance". You have, however, another problem: "Center" is singular (and has no definite article; "the"), but the verb "have" is not third person singular.
There are also some words that could be pluralised, depending on context. Thus I'd suggest:
also, the center of the leakage vortex for variable thickness blades has greater distance from the suction surface than constant thickness blades (approximately two times more).
