BS PD IEC TR 61400-12-4:2020

This part of IEC 61400, which is a Technical Report, summarizes the current state of the art innumerical flow modelling, existing guidelines and past benchmarking experience in numericalmodel validation and verification. Based on the work undertaken, the document identifies theimportant technical aspects for using flow simulation over terrain for wind application as well asthe existing open issues including recommendations for further validation throughbenchmarking tests.
