mixed convection of al 2 o 3 -water nanofluid in a square microcavity is investigated numerically. governing equations are discretized and solved using the finite volume method and simpler algorithm. the knudsen number is selected between 0.001 and 0.1 to consider slip velocity and the jump temperature boundary conditions. results showed that nusselt number is a function of richardson number, k...

Most of researches related to hydraulic jump have been done on horizontal and rough beds, and little attempt has been made on rough beds with adverse slopes. The aim of this study was to investigate the influence of rough beds with adverse slope on hydraulic jump characteristics. The variations of energy loss in stilling basins with three adverse slopes and three different roughnesses were stud...

The clique chromatic number of a graph is the smallest colors in vertex coloring so that no maximal monochromatic. In 2016 McDiarmid, Mitsche and Prałat noted around p ≈ n − 1 / 2 $$ p\approx {n}^{-1/2} random G , {G}_{n,p} changes by Ω ( ) {n}^{\Omega (1)} when we increase edge-probability o {n}^{o(1)} but left details this surprising “jump” phenomenon as an open problem. We settle problem, is...
