A polymer molecular weight distribution growth calculating method in a non-ideal flow comprises: a step of introducing a CFD compartment model that locally averages flow information of computational fluid dynamics (CFD); and a step of converting a population balance equation (PBE) of a polymer into a probability generating function (PGF) to calculate it in parallel in the z-domain inside a polymer polymerization reactor. 비이상 유동내 고분자 분자량 분포 성장 계산 방법은, 고분자 중합 반응기 내부에서, CFD(Computational Fluid Dynamics)의 유동정보를 국지적으로 평균화하는 CFD 구획 모델(compartment model)을 도입하는 단계, 그리고 고분자의 개체군 수지식(PBE, population balance equation)을 확률생성함수(Probability Generating Function, PGF)로 변환하여 z-도메인에서 병렬적으로 계산하는 단계를 포함한다.
