Just as in stationary bodies.
Solve in rest frame, then Lorentz transform,

Heat transfer in fast moving bodies occurs through convection, where heat is transferred through the movement of fluid particles. In the case of fast moving bodies, the fluid particles are typically air or water molecules that move faster due to the body's motion, resulting in a higher rate of heat transfer.
The rate of heat transfer in fast moving bodies is affected by several factors, including the speed of the body, the surface area of the body, the temperature difference between the body and its surroundings, and the properties of the fluid (such as its density and viscosity).
The shape of a fast moving body can affect heat transfer by changing the body's surface area and its aerodynamics. A larger surface area allows for more heat to be transferred, while a streamlined shape can reduce the drag and increase the speed of the body, resulting in a higher rate of heat transfer through convection.
Thermal conductivity, which is a measure of a material's ability to conduct heat, plays a significant role in heat transfer for fast moving bodies. Materials with high thermal conductivity, such as metals, can transfer heat more efficiently compared to materials with low thermal conductivity, such as insulators.
Heat transfer in fast moving bodies differs from stationary bodies primarily due to the increased rate of heat transfer through convection. Additionally, fast moving bodies experience higher levels of friction and drag, which can also impact heat transfer. The shape and size of the body may also play a more significant role in heat transfer for fast moving bodies compared to stationary bodies.
