Thermal analysis of mass concrete embedded with double-layer staggered heterogeneous cooling water pipes

Precise simulation analysis of the thermal field in mass concrete with a pipe water cooling system

“…The trend of the simulated and actual monitoring cooling progress in mass concrete was in good agreement with the designed cooling process. Obviously, the temperature recovery observed at late ages by other researchers [8] was impeded with the help of the automatic adjustment of water cooling by the TCDSS. The simulation results of the HFCM model can accurately reflect this cooling process in mass concrete.…”

“…Although this is an approximation method, it requires only simple programming and exhibits high computational efficiency. The equivalent equation is widely used in practical engineering projects [7,8]. Kim et al [9] implemented a line element for the precise modeling of the cooling pipe and applied internal flow theory to thermally analyze concrete structures with pipe cooling.…”

Boolean-Based Surface Procedure for the External Heat Transfer Analysis of Dams during Construction

“…where is the temperature; is the thermal conductivity, which is always considered isotropic in concrete material; that is, = = = ; is the internal heat source produced per volume, homogeneously distributed over the concrete. generally consists of two main parts: hydration heat generation and the cooling effect of embedded coolpipes, which was investigated in our previous work [14,17,20].…”

“…The finite element (FE) method is widely used to simulate the thermal problem of dams during the construction phase. Numerous relevant studies address the FE method [2,[12][13][14][15][16][17][18][19][20][21]. Cervera et al [12] translated a 3D thermal problem into a 1D/2D FE analysis problem by simplifying the longitudinal direction.…”

An extended finite element method for pipe-embedded plane thermal analysis

“…In conventional finite element analysis, extremely refined meshes have to be generated around the pipe axis to obtain precise thermal field. Numerous numerical studies have been conducted to analyze the temperature field in mass concrete embedded with cooling pipes [15][16][17][18][19][20][21][22][23][24]. Among them, Zhu was the first to systematically propose a finite element flow for the pipecooling problem with a refined network of FEM meshes near the pipe [15].…”
