In this research, the temperatures of three-dimensional (3D) protruding heaters mounted on a conductive substrate in a horizontal rectangular channel with laminar airflow are related to the independent power dissipation in each heater by using a matrix G+ with invariant coefficients, which are dimensionless. These coefficients are defined in this study as the conjugate influence coefficients (g+) caused by the forced convection-conduction nature of the heaters’ cooling process. The temperature increase of each heater in the channel is quantified to clearly identify the contributions attributed to the self-heating and power dissipation in the other heaters (both upstream and downstream). The conjugate coefficients are invariant with the heat generation rate in the array of heaters when assuming a defined geometry, invariable fluid and flow rate, and constant substrate and heater conductivities. The results are numerically obtained by considering three 3D protruding heaters on a two-dimensional (2D) array by ANSYS/FluentTM 15.0 software. The conservation equations are solved by a coupled procedure within a single calculation domain comprising of solid and fluid regions and by considering a steady state laminar airflow with constant properties. Some examples are shown, indicating the effects of substrate thermal conductivity and Reynolds number on conjugate influence coefficients.

增强对流输注 (CED) 是一项颇具前景的技术,其借助压力驱动流来增强输注药物进入细胞间隙的穿透力。为进一步提升CED的药物分布容积,笔者发明了一种可产生局部亚致死热量的光纤微针装置。本文试图在琼脂糖组织模型中对该技术进行定量表征。在15 °C、20 °C、25 °C和30 °C的恒温条件下,染料的输注在质量分数为0.6%的琼脂糖组织模型中进行分析。输注指标通过自定义阴影成像技术和图像处理算法进行定量。利用所获数据构建一个分布容积的经验预测时序模型作为组织模型温度的函数。接下来通过一组概念验证实验来评估液体输注时新型光纤装置产生局部光加热的能力。恒温输注显示温度和分布容积呈正相关,在100 min时,在30 °C恒温条件下体积扩散是在15 °C恒温条件下的7倍。在光加热 (1064 nm,500 mW) 过程中,输注呈现相似的效果:与对照组 (0 mW) 相比,输注体积在4 h时增大了3.5倍。本文的分析和结果为体积扩散的热介导增强提供了特征描述及新思路。
