Numerical analysis of oil-suction cavitation in the working chamber of an axial piston pump involves simulating fluid flow and pressure distribution to understand and predict the occurrence of cavitation. Here is a step-by-step overview of the numerical analysis process: 1. Geometric modeling: Create a 3D model of the working chamber of the axial piston pump, including pistons, cylinders, valve plates and other related components. Make sure the model accurately represents the geometry and dimensions of the pump. 2. Fluid flow simulation: use computational fluid dynamics (CFD) to technically solve the control equations of fluid flow in the studio. The Navier-Stokes equations are usually solved numerically, supplemented by appropriate turbulence models and, if applicable, multiphase flow models. 3. Boundary conditions: Define the appropriate boundary conditions for the simulation. Specify inlet conditions (such as flow or pressure) and outlet conditions. Consider the viscosity and compressibility of the fluid, as well as the operating parameters of the pump. 4. Cavitation models: Incorporate cavitation models into simulations to predict the occurrence and behavior of cavitation. These models take into account factors such as pressure, temperature, fluid properties, and bubble formation, growth, and collapse. 90R180-KA-5-NN-80-T-M-F1-J-03-FAC-20-20-22 90R180KA5NN80TMF1J03FAC202022 90-R-180-KA-5-NN-80-T-M-F1-J-03-FAC-20-20-22 90R180KA5NN80TMF1J03FAC202022 90R180-KA-5-NN-80-T-M-F1-J-03-NNN-38-38-24 90R180KA5NN80TMF1J03NNN383824 90-R-180-KA-5-NN-80-T-M-F1-J-03-NNN-38-38-24 90R180KA5NN80TMF1J03NNN383824 90R180-KA-5-NN-80-T-M-F1-J-05-NNN-38-38-24 90R180KA5NN80TMF1J05NNN383824 90-R-180-KA-5-NN-80-T-M-F1-J-05-NNN-38-38-24 90R180KA5NN80TMF1J05NNN383824 90R180-KN-1-AB-80-T-C-F1-J-05-FAC-29-29-24 90R180KN1AB80TCF1J05FAC292924 90-R-180-KN-1-AB-80-T-C-F1-J-05-FAC-29-29-24 90R180KN1AB80TCF1J05FAC292924 90R180-KN-1-AB-80-T-M-C8-H-05-NNN-35-35-24 90R180KN1AB80TMC8H05NNN353524 90-R-180-KN-1-AB-80-T-M-C8-H-05-NNN-35-35-24 90R180KN1AB80TMC8H05NNN353524 90R180-KN-1-BC-80-T-M-C8-J-03-FAC-35-35-24 90R180KN1BC80TMC8J03FAC353524 90-R-180-KN-1-BC-80-T-M-C8-J-03-FAC-35-35-24 90R180KN1BC80TMC8J03FAC353524 90R180-KN-1-CD-80-D-M-F1-L-05-FAC-35-35-24 90R180KN1CD80DMF1L05FAC353524 90-R-180-KN-1-CD-80-D-M-F1-L-05-FAC-35-35-24 90R180KN1CD80DMF1L05FAC353524 90R180-KN-1-DE-80-T-C-F1-H-00-FAC-35-35-22 90R180KN1DE80TCF1H00FAC353522 90-R-180-KN-1-DE-80-T-C-F1-H-00-FAC-35-35-22 90R180KN1DE80TCF1H00FAC353522 90R180-KN-1-DE-80-T-M-C8-J-03-NNN-42-42-24 90R180KN1DE80TMC8J03NNN424224 90-R-180-KN-1-DE-80-T-M-C8-J-03-NNN-42-42-24 90R180KN1DE80TMC8J03NNN424224 90R180-KN-1-NN-80-S-M-F1-H-03-FAC-35-35-24 90R180KN1NN80SMF1H03FAC353524 90-R-180-KN-1-NN-80-S-M-F1-H-03-FAC-35-35-24 90R180KN1NN80SMF1H03FAC353524 5.
