When it comes to rxjava/reactor comparison, there are quite a few perspectives. I assume you have some familiarity with both of these libraries. Obviously, they both support basic operators like map(), filter(), flatmap(), as well as more advanced.
Co-current flow is the flow in which both the fluid streams enter the equipment in the same direction whereas for in the counter-current flow the streams enter at opposite ends of the equipments. In chemical engineering most of the operations are counter-current in nature because, the mass transfer or heat transfer will be maximum in the counter-current flow.

Background: dialysate fluid connection to the membrane in continuous dialysis may affect solute clearance. Although circuit connections are routinely made counter-current to blood flow in intermittent dialysis, no study has assessed the effect of this dialysate fluid flow direction on removal of small solutes creatinine and urea during treatment using continuous veno-venous haemodialysis (cvvhd).
As the blood flows in the opposite direction to the water, it always flows next to water that has given up less of its oxygen. This way, the blood is absorbing more and more oxygen as it moves along.
A pilot scale circulating concurrent-flow dryer(200 kg/batch) was used to verify the fitness of the simulation program.
One of the most critical factors in the efficiency and effectiveness of a shell and tube heat exchanger is flow pattern. Flow pattern refers to the direction that the tubeside fluid runs in relation to the shellside fluid.
Counter current air flow is when the air flows in the opposite direction of the material flow. In this design, the material is heated gradually while traveling through the kiln.

It gives a higher value for log mean temperature difference than either a parallel flow heat exchanger or a cross.
Two solid pyrolysis models are employed in a concurrent-flow flame spread model to compare the flame structure and spreading characteristics. The first is a zeroth-order surface pyrolysis, and the second is a first-order in-depth pyrolysis.
Concurrent flow, equal speeds here we model the situation where both the high and low concentration fluids are moving through the pipes in the same direction and at identical speeds. This is identical to the situation where the fluids are not moving at all, but are left in contact with each other for a finite period of time.
Countercurrent flow heat exchangers, also known as counter flow heat exchangers, the difference between recuperative and regenerative heat exchanger.

Mar 1, 2012 greater exchange of heat or chemicals between the fluids occurs when the flows are in opposite directions (countercurrent) than in the same.
Concurrent analysis of dna and rna by flow cytometry provides information on the dna content and the transcriptional status of cells. This can be accomplished using metachromatic fluorochromes that bind to dna by intercalation and to single-stranded rna electrostatically.
Draw a picture of countercurrent flow for gas exchange with blood in fish gills, describing its advantage as compared to concurrent flow.
The difference between parallel flow and countercurrent flow; how countercurrent flow increases the rate of gas exchange.
May 31, 2019 streamflow records from the qppq transform method and those measured at usgs gages were compared for the years with concurrent flow.
In concurrent flow, where the outside fluid heats the fluid in the pipe, or vice versa. Constant heat flux should not be confused with constant surface temperature, where the latter is closely approximated when there is a phase change in one of the fluids, or when the fluids are in co-current flow.
These quantities are compared with a theoretical model describing concurrent flame spread over thin solids in low-speed flows. The paper also discusses the similarity and difference between concurrent-flow and opposed-flow flame spread in microgravity and between low-speed and high-speed concurrent-flow flame spread.

In the comparison to be presented, steady concurrent-flow flame-spread is to be compared with steady opposed-flow flame-spread in a forced-flow environment. Although concurrent flame-spread is generally considered more rapid than the opposed-flow mode, as the oxidizer flow direction favors flame propagation, there is a limiting flow velocity below which no concurrent-flow flame-spread can be sustained.

The log mean temperature difference (lmtd) is calculated using the equation for the counter current flow pattern (unless it is a completely single path parallel.
The rate of heat transfer is higher if the difference between the hot fluid (air or liquid) why is heat transfer in a counter-current flow better than in a parallel flow?.
As a brief description; the term refers to the relationship between the flow directions of the hot and cold fluids. With parallel flow the fluids are travelling through the heat exchanger in the same direction where as a counter flow installation will have the fluids flowing against each other in opposite directions.
Note that i chose to go for that solution (as a greedy magazine publisher) because if we use a virtually-infinite buffer it’s difficult to understand all the concepts of the reactive approach, and the code would look plain and simple, being hard to compare it with alternate solutions.
The most common arrangements for flow paths within a heat exchanger are counter-flow and parallel flow. A counter-flow heat exchanger is one in which the direction of the flow of one of the working fluids is opposite to the direction to the flow of the other fluid.
Extraction in a stratified counter-current flow has been studied experimentally and it has been shown to be more effi- proaches to determining mass transfer coefficient are compared.

(optional) turn on network throttling to exaggerate the effects of this comparison. While holding down the alt key, select the button, and then watch the network traffic. The tools show four requests performed in series, similar to this example.
Crossflow, parallel flow, and counterflow heat exchanger configurations are three examples. A counterflow heat exchanger will require less heat exchange surface area than a parallel flow heat exchanger for the same heat transfer rate and the same inlet and outlet temperatures for the fluids.
