TY - JOUR TI - Semi-derivative integral method to transient heat conduction: Time-dependent (power-law) temperature boundary conditions AU - Hristov Jordan Y JN - Thermal Science PY - 2021 VL - 25 IS - 5 SP - 3557 EP - 3568 PT - Article AB - Transient heat conduction in semi-infinite medium with a power-law time-dependent boundary conditions has been solved by an integral-balance integral method applying to a semi-derivative approach. Two versions of the integral-balance method have been applied: Goodman’s method with a generalized parabolic profile and Zien’s method with exponential (original and modified) profile.
