The unit of heat is joule (J) in SI unit system and calorie is used in BTU system of units. For heat transferred, watt is the standard unit.
Thermal conductivity is the amount of heat conduction by a material. To know more about the formula, units used and thermal conductivity of the metals, please visit BYJU’S

We apply a periodic heat flux boundary condition along the x direction19 and a specular boundary condition in the y and z directions so that the computational domain represents a unit cell that is repeated in all directions. Three grain boundaries (blue, green and pink plane in Fig. 1(a))...

Introduction to Heat Transfer by Incropera and DeWitt define Intensity to be "Rate of radiant energy propogation in a particular direction, per unit area normal to the direction, per unit solid angle about the direction." Units of W/(m^2*sr). Also, about flux, it normally doesn't incorpor...
protection of the melt from its environment (as for instance in an enclosed low-pressure casting unit); 3. when undisturbed, the melt may continue to be protected from the environment by its oxide and create little additional surface oxide by reaction with water vapour or hydrocarbon gases with...
