Based on the physical numerical modeling of the flow field of the muffler in this paper, the author simulated the field by numerical method with Fluent and analyzed the effect which the internal flow field has on the performance of the muffler, which may be a credible guidance of the muffler structural design.
In most of real-world applications, such as the case of heat stores, inlet is not kept at a constant temperature but it may vary with time during charging process. In this paper, a vertical water jet injected into a rectangular storage tank is measured experimentally and simulated numerically. Two cases of study are considered; one is a hot water jet with uniform inlet temperature (UIT) injected into...
Miniaturization is the trend in analytical chemistry and life sciences. In the past two decades, miniaturization of fluid handling and fluid analysis has been emerging in the interdisciplinary research field of microfluidics. Some of the microfluidic applications are drug delivery, lab-on-a-chip, pharmaceutical development, synthesis of amino acids etc. Most of these applications are used for biochemistry...
The turbulent flow characteristic in jet mixer was predicted based on CFD method adopted RNG k - ε turbulent model. Some detailed information about the velocity and turbulence kinetic energy was obtained. The results show that normalized centerline velocities at different jet velocities have the similar distribution. With the distance increasing, it gradually decreases and the curve is to be smoother...
In this paper, the turbulent flow over a triple forward facing step configuration was investigated numerically. To that end, numerical simulations are performed for 4 Re numbers and 36 different geometries. Turbulence is modeled in all simulations using the Standard k-?? model. The resulting flow field is examined in terms of pressure coefficient, vorticity and turbulent kinetic energy. Furthermore,...
In this paper presented pressure drop characteristics in one channel of plate heat exchanger by experimental method. Plate Heat Exchanger (PHE) applied in vacuum evaporator for product fresh water. PHE have become popular in chemical, power, food and refrigeration industries due to the efficient heat transfer performance, extremely compact design and flexibility of extend or modify to suit changed...
