The thermal and fluids science was analyzed through three governing equations such as continuity, momentum, and energy equations with the time terms. The difficulties to estimate the local phenomena in every moment, and location, however, would lead the unpredictable, unreasonable, and unreliable numerical results from the transient term of governing equations, turbulent flow, multiphase, interfacial phenomenon, mass and heat transfer with micro/nanoscale, and phase change heat transfer. As computer technology evolved, computing power increased dramatically and lead to lots of conductance through direct solving of problems of thermal and fluids science, however, it would also need experimental validations. Now a day, the experimental technique and measurement could provide the exact boundaries, and varying conditions with more precise, and high temporal resolutions. Through the collaboration of experiments and computations, we would like to put the footprint on the validations of thermal and fluids science research fields.
