TY - JOUR TI - Estimation of the length constant of a long cooling fin by an ancient Chinese algorithm AU - Xu Lan JN - Thermal Science PY - 2011 VL - 15 IS - 11 SP - 149 EP - 152 PT - Article AB - In this paper, an ancient Chinese algorithm is used to estimate the length constant of a long cooling fin, and an approximate solution formulation is obtained. The obtained results show that this method is a simple but promising method without any requirement for advanced calculus.
