Estimation of Transient Boundary Heat Flux Using Modified JAYA Algorithm in Laminar Duct Flow

Abstract

The major focus of paper is estimation of heat flux varying with time for two-dimensional forced convective laminar duct flow by using inverse heat transfer technique. Simple JAYA and modified JAYA algorithms are used for solving the inverse problem. JAYA is a newly developed algorithm with simple structure and does not require any tuning parameters. Modified JAYA algorithm is a combination of two algorithms where JAYA algorithm is coupled with multi-population JAYA algorithm. In multi-population JAYA algorithm, total population is divided into groups. These groups are used to estimate the required quantity. Solution of simple JAYA algorithm will be the input parameters for multi-population JAYA algorithm. Different types of heat flux profiles like step profile, smooth profile, triangular profile and linearly increasing profile are considered and performance of JAYA and modified JAYA considered. Results show that modified JAYA algorithm is found to be more accurate than JAYA.
