TY - JOUR TI - Temperature distribution of an infinite slab under point heat source AU - Wu Zhao-Chun AU - Cheng Dao-Lai JN - Thermal Science PY - 2014 VL - 18 IS - 5 SP - 1597 EP - 1601 PT - Article AB - The temperature field in an infinite slab under an instantaneous or continuous point heat source is studied numerically. The numerical results reveal the temperature distribution and its change regularity, which are significant for the temperature control encountered in many practical manufacturing processes, such as the laser treatment processes on the surface of films, welding and cutting, and even the design of measuring devices for thermal properties of material.
