After the conching is complete and the chocolate paste is formed. Then, tempering process will take over in the production of chocolate. Basically, tempering chocolate involves putting it through a cycle of temperatures which involve heating, cooling and resting under controlled conditions to produce an even crystallization of the ingredients throughout the chocolate in the most stable form. During the process, temperature, time, and agitation are the three essential variables that influence the size, type, and number of cocoa butter crystals being formed. Temperature is a significant due to there are specific temperatures for formation and melting of cocoa butter crystals.
Variable temperature, Concentration and variable mass diffusion required discussion according to Numerical solutions. The velocity field is discussed for the chemical reaction parameter, phase angle, thermal and mass Grashof number in Figures 1-7. The mass diffusion Equation (10) can be adjusted to meet that one takes (i) K > 0 means the destructive reaction, (ii) K < 0 means the generative reaction (iii) K = 0 means no reaction. The steady – state profile for different phase angle are shown Figure.1. The velocity profiles presented are those at X=1.0.Decrease in velocity with increasing phase angle.
Hence, turbulence intensity was kept 5% for pressure outlet with turbulent viscosity ratio of 10. Here, discretized model was exported to ANSYS Fluent 14.0 for solving the problem. As study was performed with velocity of vehicle at 40 m/s, the flow would be incompressible with variations in pressure around the body surface without altering the density of surrounding fluid. Hence, pressure based solver was employed with absolute velocity formulation and steady state flow
2.9 Viscosity: The property of a fluid that measure its resistance to variation of shape is called viscosity.it is indicated by μ. 2.10 Density (mass density): It is ratio of mass of fluid to the volume of fluid. Mathematically: 2.10 Nanofluid: Nanofluid is mixture of nanoparticle and base fluid, nanoparticle consist of Fe (iron),Cu(copper),SWCNT,MWCNT and base fluid include ethylene , glycol , pump oil etc. Nanofluid have higher thermal conductivity than their base fluid. 2.11 Nanoparticles: Nanoparticles are particles between 1 and 100 nanometer in size (nanometer is unit of length in metric system equivalent to one billionth of a meter (0.000, 000,001) representation is nm.

It is observed that, as the porosity of the bounding surface increases the velocity also
By implementing the second law of motion the particle will accelerate or decelerate if there exists a pressure difference over the particle. The particle’s velocity will increase when it is approaching a low-pressure region and decrease its velocity at a high-pressure region. This principle can also be seen in terms of pressure. If a fluid is slowed down in the pipe the pressure will rise and vice versa. This principle is applicable to the basic way an aircraft’s wing is able to generate lift (Figure 10).
Mass is how much material an object has. (Singh, Lakhmir, 2012) It is the only variable that will be changed throughout the experiment. The dependent variable is what one observes or measures. The dependent variable in this experiment is the tangential velocity. The relationship of tangential velocity and the mass of the object will be observed
It shows that the micro-bubble fluid front, flows with constant speed. This is agree with literature experiments, except when the capillary effects occurs. The Figure 2 shows the bubble density versus bubble generation parameter. It indicates that, any increasing in bubble generation, increase the bubble density at specified
• To analyze the temperature dependence of viscosity by using a vibro viscometer. METHOD AND MATERIAL Capillary Viscometer By using Cannon-Fenske (U tube) viscometer, the experiment was performed for pure water and cherry juice. During this part of experiment, spherical chamber is filled with liquid and then the liquid was pulled up to upper elliptical chamber by means of puar being removed from system. Time data were recorded as well as the viscometer size. Brookfield Viscometer This procedure was followed to measure the viscosity of baby food sample by observing the shear stress vs. shear rate relationship with Brookfield viscometer.
Fig.1 Fig.1 Visualization of a moving Fluid Fluid dynamics often offers a systematic structure—that embraces empirical and semi-empirical laws derived from flow measurement and used to solve practical problems. The solution to a fluid dynamics problem, typically involved calculating various properties of the fluid, such as velocity, pressure, and temperature, density as functions of space and time. Applications of Fluid Mechanics 2.1 Bernoulli 's Principle in Action: As fluid moves from a wider pipe to a narrower one, the volume of the fluid that moves a given distance in a time period given does not change. But as the width of the narrower pipe is smaller, the fluid must move faster (that is, with greater dynamic pressure) in order to move the same amount of fluid the same distance in the same amount of time. Observe the behavior of a river: in a wide, unconstructed region, it flows slowly, but if its flow is narrowed by canyon walls, it speeds
