We consider the initial-boundary value problem of compressible Navier–Stokes–Vlasov equations under a local alignment regime in a one-dimensional bounded domain. Based on the relative entropy method and compactness argument, we prove that a weak solution of the initial-boundary value problem converges to a strong solution of the limiting two-phase fluid system. This work extends in some sense the previous work of Choi and Jung [Math. Models Methods Appl. Sci. 31(11), 2213–2295 (2021)], which considered the diffusive term ∂ ξξ f ɛ in the kinetic equation. Note that the diffusion term was not considered in this paper.

We are concerned with the analysis of a mean field type equation and its linearization, which is a nonlocal operator, for which we estimate the number of nodal domains for the radial eigenfunctions and the related uniqueness properties.

For $nu,nu_i,mu_jin(0,1)$, we analyze the semilinear integro-differential equation on the one-dimensional domain $Omega=(a,b)$ in the unknown $u=u(x,t)$ [ mathbf{D}_{t}^{nu}(varrho_{0}u)+sum_{i=1}^{M}mathbf{D}_{t}^{nu_{i}}(varrho_{i}u) -sum_{j=1}^{N}mathbf{D}_{t}^{mu_{j}}(gamma_{j}u) -mathcal{L}_{1}u-mathcal{K}*mathcal{L}_{2}u+f(u)=g(x,t), ] where $mathbf{D}_{t}^{nu},mathbf{D}_{t}^{nu_{i}}, mathbf{D}_{t}^{mu_{j}}$ are Caputo fractional derivatives, $varrho_0=varrho_0(t)>0,$ $varrho_{i}=varrho_{i}(t)$, $gamma_{j}=gamma_{j}(t)$, $mathcal{L}_{k}$ are uniform elliptic operators with time-dependent smooth coefficients, $mathcal{K}$ is a summable convolution kernel. Particular cases of this equation are the recently proposed advanced models of oxygen transport through capillaries. Under certain structural conditions on the nonlinearity $f$ and orders $nu,nu_i,mu_j$, the global existence and uniqueness of classical and strong solutions to the related initial-boundary value problems are established via the so-called continuation arguments method. The crucial point is searching suitable a priori estimates of the solution in the fractional H"{o}lder and Sobolev spaces. The problems are also studied from the numerical point of view.
