Experimental Investigation on the Effection of Flow

2014-9-16densed vapor from Cond 2 may exist and flow through the LL When the vapor reaches the FR it will be pre-vented by FR and other excess vapor flow will turn to flow through Cond 1 where it will be condensed to liquid and flow through the porous structure In this way the mass flow rate can be controlled and the operating tem-perature descends

A Experimental Investigation of the Structure of a

The structure of a turbulent reattaching flow behind a backward-facing step was studied experimentally in a low-velocity water channel in order to observe the physical structure of the flow and to better understand the relation between this physical structure and measured turbulence quantities Flow visualization using the hydrogen bubble technique was used to observe the physical structure

Experimental and Numerical Investigation of Flow

Abstract Based on the principle of the critical flow and standard k-three-dimensional turbulence model experiments and simulations were performed on a portable pillar-shaped flume with three contraction ratios under 12 working conditions By combining the numerical simulations with the experiments the theoretical stage-discharge formula of the portable pillar-shaped flume was developed and

Experimental and numerical investigation of flow

2019-7-1This experimental technique is still more advanced than many others due to its ability to capture velocity zones instead of individual point measurements to trace the movement of particles seeded in working fluid and to enable analyzing the flow structure in details in a given time period

Experimental Investigation of Three‐Dimensional Flow

A similar experimental technique had been employed previously by Chrisohoides et al and Kang and Sotiropoulos for visualizing the free surface flow structure in an open‐channel flow In Figure 18 a– 18 e it is observed that the paper confetti released at different upstream locations converge to a single line of flow convergence
