中文摘要a three-dimensional analytical solution of the microheater temperature based on heat diffusion equation is developed and compared with experimental results. dimensionless parameters are introduced to analyze the temperature rise time and the distribution under steady state. to study the microheater temperatures before bubble nucleation, a set of working fluids and microheaters are considered. it is shown that the dimensionless time xi(-)(0) required for the temperature rise from room to 95% of the steady state temperature is about 75, not dependent on working fluids and microheaters. heat transfer to the surrounding liquid is mainly caused by conduction, not by convection and radiation mechanisms. the microheater length affects the surface temperature uniformity, while its width influences the steady temperatures significantly, yielding the transition from heterogeneous to homogeneous nucleation mechanism from square microheaters to narrow line microheaters.
