In this paper the characteristics of unsteady three-dimensional incompressible flows with heat transfer are obtained along with artificial compressibility of Chorin. At first, compatibility equations and pseudo characteristics for three-dimensional flows are derived from five governing equations (continuity equation, Momentum equations in three directions, and energy equation) and then results ...

The object of the study is process grinding metal shavings during transportation by a screw conveyor under condition using common drive in order not to increase energy consumption.In work, fundamentally new scheme for drain chips and chipping was proposed, calculation knife crusher developed, kinematic which uses involved torque thanks power take-off shaft save consumption resource conservation...

Mesin stone crusher digunakan untuk memproduksi agregat, yang menjadi salah satu bahan utama dalam pembuatan beton. Permasalahan saat ini sedang dihadapi perusahaan Abipraya Beton adalah loss time mesin besar pada dan belum dapat memenuhi kuantitas kualitas diharapkan oleh perusahaan. tersebut fokus penelitian meningkatkan efektivitas dengan pendekatan Total Productive Maintenance (TPM). Langka...

Let $X$ be a  Banach  space, $Csubset X$  be  a  closed  convex  set  included  in  a well-based cone $K$, and also let $sigma_C$ be the support function which is defined on $C$. In this note, we first study the existence of a  bounded base for the cone $K$, then using the obtained results, we find some geometric conditions for the set  $C$,  so that ${mathop{rm int}}(mathrm{dom} sigma_C) neqem...

The article deals with the production of polystyrene concrete from recycled crushed in a rotary crusher waste foam packaging. resulting can be attributed to thermal insulation, used for insulation load-bearing structures buildings, as well structural and bearing layer outer walls low-rise buildings. dependence conductivity sample on density strength has been established, resistance shock loads ...
