Abstract:

In this paper, we present a novel design scheme of temperature-jump (T-jump) area for microfluidic device. Numerical simulation and experimental research of thermal characteristics of the solution in microchannels is completed. Numerical simulation of the temperature-jump microchannel is analyzed to study the heat transfer characteristics by comparing performance of three proposed configurations. Calculation of the power requirement is discussed in the dimensional design of microheater. Temperature-sensitive fluorescent dye is applied to investigate the temperature field of microchannel heated by a designed microheater. It is found that the T-jump microfluidic device can provide rapid heating for solutions with strong convection heat transfer ability.
