Abstract ：
In this article, a clear and concise analytical method for predicting the performance of a Liquid-cooling eddy current brake (LC-ECB) is proposed. The LC-ECB has a coolant channel in the rotor to allow direct cooling of the inner surface of the stator. The static air-gap magnetic field distribution is obtained by the dynamic magnetic equivalent circuit (MEC) method, and the magnetic flux leakage and global magnetic saturation effects are fully considered. The magnetic field intensity distribution function of the eddy current reaction magnetic field is derived for the first time based on Ampere circuital theorem. Considering the local magnetic saturation and skin effect, a novel double-iteration algorithm based on the conservation principle of magnetic pressure drop is applied to obtain the transient air-gap flux density distribution, and then the brake torque expression is obtained. The finite element method (FEM) and experimental results show that the proposed method is feasible and effective. The new model is easy to program and can be easily used in the initial design and optimization of LC-ECB.

Abstract ：
This paper proposes an electromagnetic damping generator (EDG), which is a novel downhole generator for the rotary steerable system (RSS). The EDG is designed to solve the problem of unstable voltage output by the RSS generator. The generator is designed by integrating a traditional generator and an eddy current retarder (ECR). The system converts the excess kinetic energy of the EDG rotor into heating energy by the principle of eddy-current braking and resistance heating. The electromagnetic finite element models of the generator part and ECR part are established and solved by computer. The voltage and torque generated by the generator part and the braking torque of the ECR part are predicted. In the bench test, When the input power is 2537 W < P-input < 3304 W, the EDG is able to output 300.8 V. When the input power is 3304 W, the output voltage of the ordinary generator is 346 V. The EDG can be adjusted by a decrement of up to 45.2 V to output the rated voltage. The problem of generator output voltage instability in the RSS is solved when mud flow is unstable.

Abstract ：
To solve theproblems of an insufficient braking moment for the eddy current retarder at high speed, a small braking moment and slow response of the hydraulic retarder at low speed, and a low power density of the existing electromagnetic hydraulic retarder(EHR), a novel radially distributed electromagnetic-hydraulic retarder(R-EHR) was proposed. The R-EHR fully absorbs the advantages of the braking characteristics of hydraulic retarders and eddy current retarders. The cooling fluid is used to realize the braking of the hydraulic part. At the same time, it acts on the heating surfaces to improve the torque of the electromagnetic part. In this paper, finite element models of the flow field and electromagnetic field are established to predict braking performance. The braking performance of the R-EHR is obtained by bench test, the error between the simulation and experimental data is compared, and the experimental data are analyzed. The results show that the proportion of electromagnetic braking torque in the novel R-EHR is more reasonable. The braking torque increased by 26% and the power density increased by 37.5% at 2000 RPM compared to that of the EHR. The R-EHR can control the braking torque only by adjusting the current, thus simplifying the control system.

Abstract ：
The retarder is widely used to ensure braking safety in heavy vehicles due to its noncontact braking characteristics. Currently, retarders are generally mounted on tractors, but semi-trailers have greater inertia and are prone to accidents. Therefore, the semi-trailer's brakes have to work frequently to maintain stability during downhill braking, which causes the brakes to generate high temperatures or even failure. Based on the above problems, a novel internal pump-hydraulic retarder axle (IP-HRA) is proposed, which integrates the pump and hydraulic retarder (HR) into the support axle. The prototype of the IP-HRA was made and a bench test was conducted. In the experiment, the single-side braking power of the IP-HRA reaches 300 kW and its torque can be controlled by adjusting the outlet pressure. A co-simulation model of articulated vehicles is established to predict the braking state by computer solutions. Based on the experimental data, the methods of IP-HRA braking semi-trailer and traditional HR braking tractor are compared. The results of co-simulation show that the IP-HRA is more conducive to the braking stability of the articulated vehicle than the traditional HR when only retarder is used. Finally, the braking time and braking deceleration of IP-HRA are verified by road experiments.

Abstract ：
This paper proposes a new concentration gradient generator based on the principle and flow characteristics of solution mixing in the microchannel. This concentration gradient generator works with oscillating bubbles in the microchannel, which are excited with bulk acoustic wave. The oscillating bubbles are used to mix the solution in the microchannel. The volume of each bubble is controllable individually and the number of bubbles partaken mixing is adjustable. Therefore, the mixing position of the solution and the concentration gradient in the microchannel are adjustable. Therefore, the new concentration gradient generator has the advantages of fast response and high flexibility. Simulation software COMSOL 5.5 was used to simulate the influence of the inlet flow rate, the bubble amplitude, and the number of bubbles on the mixing result. The simulation result shows that the inlet flow rate and the bubble amplitude affect the mixing width of the solution in the microchannel. The simulation result also shows that the concentration distribution with different gradient can be generated by adjusting the number of bubbles located in the solution microchannel. The simulation has an important reference for the design of the concentration gradient generator.
