| 5L Heat pipe bioreactor is exploited using high performance heat transfer element-heat pipe, flow profile of the reactor is also measured by Particle Image Velocimetry(PIV). The mathematical of momentum transfer and heat transfer in the reactor is fitted, which is based on Computational Fluid Dynamics and the experiment data of flow profile and temperature profile in the reactor, it will provide the analysis, exploitation and scale design of the reactor in industry with the basic mathematic model.The typical flow profile in the agitated reactor is measured successfully and originally by PIV technology, which will not only provide mature experiment measuring technique of flow profile for agitated reactor, but also provide the quantitative-full realization, analysis and simulation of momentum transfer process in HPBR with the basic experiment data. In the state of laminar flow(mix-rotate is 50r/min), the velocity and vorticity of uniformity phase Newtonian fluid is minor, but its flow profile is well distributed, mixture of flow is plenary, its fluid state is typical: flow of cylindrical does uniform motion from top to bottom in the middle of reactor (R/Rm=0~0.6), the flow of impeller area section does uniform motion along radial direction, flow of other sections does motion which is deviate radial direction or similar with circular motion; The flow doing axial decurrent motion meets the bottom of reactor and shoots all around at perimeter, then rebounds to upflow, which causes the velocity of decurrent flow in the cylindrical of R/Rm=0.6~0.75 to reduce to 0, while the flow in the perimeter cirque of R/Rm>0.75 whose motion is from bottom to top meets the flow in the middle whose motion is reverse direction, which forms the process of sequence circulation flow in reactor. The upward flow of R/Rm=0. 9'has the highest velocity(which is 1.4 times than that of the flow in the middle (R/Rm< 0. 6)), the flow in the cylindrical of R/Rm>0. 9 enters the boundary quickly its radial velocity and radial velocity reduce to 0 rapidly; The degree of mixture is strengthened with speed of agitator's enhancing, compared to the velocity and the vorticity in the laminar flow state, the velocity in lower onflow state (mix-rotate is 200r/min) is geminately enhanced, its value is improved by 360% ,the vorticity is also enhanced by 140%.Compared to the velocity and vorticity in the lower flow state, they are further and respectively enhanced by 150% and 100% in superior onflow state(mix-rotate is 400r/min), mixture is acute. Compared with uniformity phase fluid, because of the action engendered by upswing, agglomeration, break and convolution of bubble which can retard flow( radial flow in especial) and prick up turbulence, the flow of fluid in low speed area is improved, the vorticity is further enhanced, the degree of mixture is improved, although the average radial velocity is decreased. Under all of the experiment operational conditions, because of agitator blade's straight forcing, fluid near the impeller has maximum velocity and vorticity, while minimum velocity and vorticity are at the march between main loop area and free surface or the boundary reactor wall and tubes, where only secondary flow has momentum transfer, the flow profile between two local areas in low onflow state is distributed markedly, the ratio of velocity is 180, the ratio of vorticity is 40.The system testing temperature profile of fluid in HPBR and heat pipe wall is set up, we measure and study effectively the whole HPBR's temperature profile of Newtonian fluid and non-Newtonian fluid. Under the onflow experiment condition, when the reaction heat is under 40kW/m3, the average temperature difference of H2O, 2%CMC, H2O-Air,2%CMC-Air etc is only 0.14,the maximum of theirs is 0.6 ; Heat pipe wall always keep good isothermal property under all experiment conditions, its maximum is only 0.3.To H2O system under all experiment conditions, when the reaction heat is under 9.6kW/m3, the system can be stabilized above 30癈 reaction temperature state by three heat...
