"concentrated region" is correct and usable in written English.
You can use it to indicate a localized area where a particular thing is especially significant or common. For example, "The city is a concentrated region of economic activity."
It is a two-step implicit explicit finite difference scheme and particularly designed to resolve flow details in the highly concentrated region at a mobile sand bed where vertical gradients of concentration and flow velocities are very large.
The parabolic shape illustrates the chemical wave projecting outward from the centre (most concentrated region) of the droplet.
In the concentrated region, the temperature dependence of scattered-light intensity exhibits a large peak just below c.m.t., which is similar to the anomalous micellization.
It has been found that Moulik's equation (ν/ν0)2 = M + KC2 holds good for these systems for the concentrated region.
Sagiya et al. (2000) analyzed the GNSS data and found a concentrated region of strain rates far from major plate boundaries including the Nankai Trough and Japan Trench in central Japan.
In the concentrated region, the ΔmE values calculated by CE and SQS methods also agree well in many cases; however, noteworthy discrepancies are found in some cases, which we argue originate from inherent elastic and dynamic instabilities of the relevant parent lattice structures.
As the particles are pushed between the growing crystals, concentrated regions of colloidal particles are formed.
The studies showed that the pulp flocs used are a composite of several concentrated regions separated by weaker interfaces.
By adding more polymer into the solution for all polymers, interaction among polymer chains will increase and solution states will be changed from dilute region to semi-dilute and concentrated regions which means higher viscosity.
The latter requires harvesting from the entire world forest areas, while the present plant and harvesting (PH, described in the Methods section) strategy is performed in concentrated regions of less than one percent of the global forest area.
It can be seen that the particles in PF are concentrated in a relatively small region and that VAPF propagates the particles in a larger scope, while the proposed tracker not only has five concentrated regions but also propagates in a larger scope (Fig. 9).
