In this study, the workability of cement-based grouts containing n-TiO 2 nanoparticles and fly ash has been investigated experimentally. Several characteristic quantities (including, but not limited to, the marsh cone flow time, the mini slump spreading diameter and the plate cohesion meter value) have been measured for different percentages of these additives. The use of fly ash as a mineral additive has been found to result in improvements in terms of workability behavior as expected. Moreover, if nano titanium oxide is also used, an improvement can be obtained regarding the bleeding values for the cement-based grout mixes. Using such experimental data, a multi-layer perceptron artificial neural network model has been developed (5 neurons in the hidden layer of the network model have been developed using a total of 42 experimental data). 70% of the data employed in this model have been used for training, 15% for validation and 15% for the test phase. The results demonstrate that the artificial neural network model can predict Marsh cone flow time, mini slump spreading diameter and plate cohesion meter values with an average error of 0.15%.

“…In other words, the cohesion-increasing effect of nano titanium oxide is limited by adding FA [9][10][11]. This limitation in the cohesion values can be considered as an improvement in the workability behavior of the respective grout mixes [68][69][70].…”

“…Ganesh Kumar et al [6] have investigated the boundary layer flows and melting heat transfer of a Prandtl fluid over a stretching surface in the presence of fluid particle suspensions. Jalali et al [7] conducted a numerical investigation of the competition between viscosity and thermal conductivity about their effects on heat transfer by Al 2 O 3 -water nanofluid. Much insight on this theme can be found in [8][9][10][11][12].…”

In this study, a radiative MHD stagnation point flow over a nonlinear stretching sheet incorporating thermophoresis and Brownian motion is considered. Using a similarity method to reshape the underlying Partial differential equations into a set of ordinary differential equations (ODEs), the implications of heat generation, and chemical reaction on the flow field are described in detail. Moreover a Homotopy analysis method (HAM) is used to interpret the related mechanisms. It is found that an increase in the magnetic and velocity exponent parameters can damp the fluid velocity, while thermophoresis and Brownian motion promote specific thermal effects. The results also demonstrate that as the Brownian motion parameter is increased, the concentration values become smaller.

“…The internal combustion engine is a machine which can convert thermal energy into mechanical energy [1], and the piston is the main heated part in the internal combustion engine. The thermal load is one of the factors that cause the piston to work abnormally, and the degree of influence of this effect increases with the increase of the strengthening index in the internal combustion engine [2]. Many scholars have used the finite element method to study the temperature field and thermal stress of the piston.…”
